Three hot spots in the new material industry
1
One of the three hot spots: Aramid, PI and PA
⏬ Aramid - a key strategic material
Aramid downstream applications high-end, is a key strategic material。
The characteristics of aramid products are high threshold, fewer domestic enterprises, obvious substitution trend of localization, and obvious upward trend of the industry at present。
The threshold of aramid products is mainly the technical and customer access threshold, to enter the market need to do safety certification, need several years of successful cases, downstream application field security requirements are very high。
目前全球的对位芳纶处于近平衡状态，国内对位芳纶80%依赖进口。From a global point of view, with the increase of application areas, the demand for para-aramid will gradually increase, and it is expected that the global demand for para-aramid will reach about 150,000 tons in the next five years。According to the annual growth rate of 10%, the demand for para-aramid in China will reach 13,000 tons in 2020, and the demand for para-aramid will reach 25,000 tons in 2025。
The global intermediate aramid industry is mainly occupied by companies such as DuPont, Taihe New Materials and Teijin of Japan。Among them, DuPont ranked first with 67% of production capacity, and Teijin accounted for 7%。
⏬ polyimide -- "Problem solver"
Polyimide is one of the organic polymer materials with the best comprehensive properties。Its high temperature resistance of more than 400℃, long-term use temperature range of -200 ~ 300℃, some no obvious melting point, high insulation performance, 103 Hz dielectric constant 4.0, dielectric loss is only 0.004～0.007, from F to H。
PI film
PI film is the earliest and most mature product in the PI series of products, and it is the best choice for insulating film, and the wave of localization of high-end products is approaching。
PI films below the electronic grade have achieved domestic self-sufficiency, and the PI film market above the electronic grade is still mainly divided by overseas companies。
With the gradual landing of domestic chemical imine production lines, domestic manufacturers will participate in sharing the high-end market of nearly 10 billion market。In the future, as the FCCL market maintains a high growth rate and the demand for flexible substrates increases with the rapid popularization of OLED, the high-end electronic grade PI film market will be in a period of rapid expansion。
PI fiber
Take root in the military market, and accelerate the development of the civilian market。PI fiber has excellent heat resistance and mechanical properties, and is the core accessory material in important fields such as aerospace and military aircraft, and its application in the military market is irreplaceable。
In the commercial field, PI fiber in environmental protection filter materials, fireproof materials and other applications are currently in the gestation period, the future is expected to add new vitality to PI fiber。
PI/PMI bubble
Benefit from the climax of warship construction, welcome the "blue ocean" era。At present, the most important application of PI foam is the heat insulation and noise reduction material for warships. At present, China's navy is in the third ship construction climax. PI foam is the preferred heat insulation and noise reduction material for new warships, and the future demand is expected to increase rapidly。In addition, as the most excellent structural foam core material, PMI foam is widely used in fan blades, helicopter blades, aerospace and other fields, and its replacement trend for PET foam is clear, and the market space is broad。
PI matrix composite material
Lightweight is the big trend, focusing on the high-end market。Fiber reinforced composite is a new generation of lightweight materials after magnesium aluminum alloy. Polyimide as a resin based composite has excellent high temperature resistance and tensile properties, and is widely used。With the gradual maturity of the carbon fiber industry, the demand for carbon fiber reinforced composite materials has increased significantly, and the combination of polyimide and carbon fiber, as one of the most excellent composite material combinations, has obvious advantages in seizing the high-end market。
PSPI(Photosensitive polyimide)
Photoresist, electronic packaging dual fields of strength, enjoy the high-end dividends of electronic products。Photosensitive polyimides have two main applications: photoresist and electronic packaging。Compared with traditional photoresist, PSPI photoresist does not need to be coated with light blocking agent, and can greatly reduce the processing process。PSPI is also an important electronic packaging adhesive。
Photosensitive polyimide as a packaging material can be used in: buffer coating, passivation layer, alpha ray shielding material, interlayer insulation material, chip packaging material, etc., but also widely used in the microelectronics industry, including integrated circuits and multi-chip packaging packages。

High temperature resistant nylon
The technical barriers to high temperature nylon are relatively high, the industry has not been large-scale development, and there is a huge gap in market demand。The research of high temperature resistant nylon in China is relatively late, and the development of new varieties is mainly based on the modification of PA6T, supplemented by the synthesis of new nylon。
High temperature nylon as a high-performance engineering material market continues to expand, it is expected that China in the next few years, the demand for high temperature nylon will grow at a rate of 15% to 25%。
The potential demand for high temperature resistant nylon accounts for 20-30% of nylon, and the demand for nylon in the Chinese market is expected to reach 10,000 tons within five years。
Nylon elastomer
Nylon elastomers are polyester/polyether-polyamide block copolymers, the most common is polyether block amide (PEBA), which is more prominent properties are high resilience, light weight and low temperature impact resistance。
The energy feedback of nylon elastomer can reach 85%, which is about 15% higher than Boost cushioning technology, and has a better shock absorption buffer effect。Compared to TPU, it is lighter in weight。
Nylon elastomer synthesis technology threshold is high, mostly in the hands of French Arkema, Germany Evonik, Japan Ube Xingko and other foreign manufacturers。
Nylon elastomer market demand potential is huge, in addition to 44 billion pairs of shoes/year substrate demand, as well as the replacement of polyurethane soft foam, plastic runway materials。
Three hot spots second: electronic chemicals
Electronic chemicals are fine chemical materials specially designed for the development, etching, cleaning and electroplating processes in the manufacture of electronic information products, and are important supporting materials for the information industry such as integrated circuits and flat panel display manufacturing。
2017年，世界Electronic chemicals产值>1500亿美元，中国产值约2600亿元，预计2018-2022年，年均增长率约为11%。Companies including Dow, Honeywell, Mitsubishi Chemical and BASF are racing to focus their electronic chemicals business on the Asia-Pacific region, including China。China's abundant raw materials and proximity to downstream demand are obvious advantages, and the transfer of electronic chemical production capacity to the domestic has become the general trend。
Three hot spots: lightweight, energy-saving materials
The key to lightweight - high-performance new materials such as TPEE, POM, PI, PA, PU, TEEK, PPA, PTT and so on to replace the proportion of steel several times。
Polymer curing technology - A research team led by Professor ScottWhite at the University of Illinois has developed a new polymer curing technology，A small heat source is needed for polymer fabrication in a short time，Compared to current manufacturing processes，Reduces energy consumption by 10 orders of magnitude，And reduce man-hours by two orders of magnitude。
Carbon fiber - lightweight while pursuing high performance。
The four major materials of the new materials industry
2
One of the four major materials: film
Material film market
China's material film industry growth is stable, 2010-2017 China's material film production increased from 7.99 million tons to 15.7 million tons, the average annual compound growth rate of 10%。
In 2017, the global sales volume of liquid crystal polymer films and laminates was about 9,050 tons, with a compound annual growth rate of 6.7%。
Express packaging film will show a reduction, green, recyclable development trend。
The optical film of the backlight module will tend to be high brightness, thin shape, light weight and high color gamut。
Optical polyester film industry
The preparation technology of functional polyester raw materials is one of the core technologies of film making enterprises, among which nano-micron addition modification, involving smooth uniformity, crystallization uniformity and static voltage film property, is the technical bottleneck that hinders the development of the industry。
At present, the domestic optical polyester film industry is still in the initial stage, most of them focus on the film stretching processing, lack of systematic research on optical polyester film technology。
It is difficult to compete with international giants in terms of optical polyester film materials (special slices and masterbatch), formula design, equipment and process control, which restrict the development of new display industries in China;Third, the overall scientific and technological innovation of the industry lacks coordination and linkage。
BOPA film industry
BOPA film is mainly used in food, daily chemical, medicine, electronics, construction, machinery and other packaging fields, of which food packaging accounts for 70%-80% of the share, mainly for high temperature cooking, freezing, leisure food。
It is expected that in the next few years, China's flexible packaging and BOPA film market will continue to show growth, and overseas markets will become another new growth point。
BOPET film industry
Because of its excellent physical and chemical properties and environmental protection properties, BOPET film is known as one of the most promising new materials in the 21st century。
China's BOPET polyester film demand accounts for 33% of the total global demand。
Downstream application industries are mainly packaging materials, electronic information, electrical insulation, card, image film, hot stamping foil, solar energy applications, optics, aviation, construction, agriculture and other production fields。
At present, the largest application field of mylar film produced by domestic manufacturers is the packaging industry, such as food and beverage packaging, pharmaceutical packaging, and some special functional mylar film is used in high-end fields such as electronic components and electrical insulation。
BOPP film industry
BOPP film has the reputation of "packaging queen", and the apparent consumption of BOPP film in China was 251 in 2013.In 2017, it has reached 3.3 million tons, an increase of 32% in 5 years。
With the continuous improvement of China's consumption level and the rapid development of post-processing color printing composite, composite film, aluminum plating, coating and other industries, the demand for BOPP film has great market potential。
BOPE film industry
BOPE film industry will become a film industry focus, which has the following advantages:
More suitable for mass order production needs;
High transparency, high gloss, few crystal points;
High stiffness, high tensile strength;
High puncture resistance;
Excellent low temperature impact strength and pinhole resistance, wear resistance, excellent low temperature flexibility;
Long wetting tension holding time, good printing performance, accurate overprinting。
Using half thickness of BOPE instead of blowing material or casting CPE film and BOPA or BOPET dry composite can achieve the same heat sealing strength and close stiffness;
In addition, half of the thickness of BOPE instead of blowing material or casting CPE film and BOPA dry composite for frozen packaging can greatly reduce the broken bag rate。
Two of the four materials: 3D printing materials
At present, the commonly used 3D printing polymer materials are polyamide, polyester, polycarbonate, polyethylene, polypropylene and ABS。Although the most common market materials for 3D printing are ABS and PLA, nylon is actually the largest material used。Nylon is expected to account for 30% of the 3D printing materials market by 2022。
The main factors affecting the application of materials in 3D printing are: high printing temperature and poor material fluidity，Volatile components appear in the working environment，Print nozzle easily blocked，Affect product precision;Ordinary materials have lower strength，The scope of adaptation is too narrow，The material needs to be enhanced;The cooling uniformity is poor，Slow setting，Easy to cause shrinkage and deformation of products;Lack of functional and intelligent applications。
Global 3D Printing Market ($100 million)
Application field analysis
The future large-scale industrial applications in the global 3D printing market is expected to usher in explosive growth。
In the industrial field, 3D printing has formed a complete industrial chain after 30 years of development。
At present, 3D printing technology has been applied in the military, aerospace, medical, automotive, mechanical equipment manufacturing and consumer fields。
3D printing is used in construction, building load-bearing parts, automotive parts, industrial parts。Every link of the industrial chain gathers a group of leading enterprises。
Development direction of 3D printing materials in China
With the development of 3D printing technology, the performance of traditional materials has been greatly improved, relying on the strong rapid melting deposition and low temperature bonding characteristics of materials will be widely used in the field of 3D printing manufacturing。In addition to the material itself can be 3D printed products, 3D printing in glass, ceramics, inorganic powder, metal, etc., needs to rely on the adhesion of the material to complete。
The strength of the modified material is used to directly replace the metal for various complex components, which is cheap and lightweight。It can even replace glass, ceramics and other products, so that the material is widely used in 3D manufacturing。
Materials can avoid the defects of low strength, and develop towards composite and functional, especially to achieve multi-material composite, thus giving materials specific functions。New materials such as smart materials, photoelectric polymer materials, photothermal polymer materials, photovoltaic polymer materials and energy storage polymer materials are manufactured by 3D printing technology。
3D printing has the advantages of rapid repair without molds and parts, which can advance China's manufacturing industry for 5-10 years, and 3D printing is a revolution in the industry。
Three of the four materials: degradable materials
Biodegradable materials subdivision applications (10,000 tons)
It is expected that by 2020, China's production of biodegradable materials will reach 2.5 million tons。The "13th Five-Year Plan", the international total carbon law, and the improvement of the performance and price of biodegradable materials will bring unprecedented development opportunities for China's biodegradable materials industry。
The complete biodegradable materials mainly include PLA, PHA, PBS/PBSA, PCL, PVA, PPE/PPC/PPB and a small part of PSM。Biodestructive materials mainly refer to the modification of traditional polyolefin by biodegradable resins, and most of PSM belongs to this category。
The development of biodegradable materials is more and more in line with the environmental protection concept of society, the current global research and development of biodegradable materials up to dozens of varieties, but to achieve batch and industrial production only PSM, PLA, PBS/PBSA, PHA, PCL and so on。
2015-2020 Global demand forecast for three major biodegradable materials
Four materials: New elastomers
Acrylyl elastomer
Allylene-based elastomer is produced by the combination of metallocene catalytic technology and solution polymerization process. It is a unique semi-crystalline copolymer of allylen-ethylene, which has unique high elasticity, flexibility and low temperature impact resistance, especially excellent compatibility with PP。
Currently, only three companies in the world have commercialized allylene-based elastomers: Dow's versify, ExxonMobil's vistamaxx, and Mitsui's tafmer。
Advantages of propylene elastomer:
Allylene-based elastomers have the characteristics of good feel, high filling, and good anti-slip, such as the foaming advantage of ExxonMobil vistamaxx;
VM foaming products have good hand feel, good density, and a gummy feeling;
With high filling, the filling amount can reach 100phr, and the filling amount of EVA is generally 30phr, which has great advantages in reducing costs and doing some functional materials, such as flame retardant materials, which rely on filling to play the performance;
It can be 100% recycled, and the foam out of the product will not appear the distribution of pores on the surface of the product is not good, and EVA foam if you add too much recycled material (generally add 30phr), there will be a bad density distribution phenomenon;
Using VM to do some relatively low hardness foaming process is much easier to operate than EVA。If the hardness of EVA is 10°C, it is very difficult, and SEBS is generally added to increase the softness, and VM is easy to do;
Improved impact strength opens up opportunities for thinning, reducing material use and reducing costs;
The acrylic elastomer has a lower melting temperature, which reduces the processing temperature, and its higher flow rate will increase the processing speed。This can reduce energy consumption and improve processing efficiency。Its flexibility helps to improve the draw ratio and reduce flow marks, resulting in better product quality and lower scrap rates。Because the shrinkage rate of this elastomer is lower than that of polypropylene, the production process is easier to control and the die cutting is more accurate, which improves the match between the cup and the lid and helps to reduce the scrap rate。
Application of propylene based elastomers:
Random copolypolypropylene (RCP) is widely used in food preservation box, but the problem of low temperature impact resistance is common。The application of propylene based elastomer to polypropylene modification can improve the toughness of polypropylene。As a toughening agent in RCP, it can improve the toughness while maintaining the transparency of RCP, and help to reduce the stress whitening of hinge structure.
The blending of propylene based elastomers with polypropylene (PP) can achieve a better balance of impact resistance, transparency and stiffness, while improving processing efficiency;
Can be used in non-woven fabric, elastic film, polymer modification, etc., of which polymer modification performance is excellent, the specific application cases are washing machine seat, food container cover, humidifier water tank, plastic stationery, sports kettle, slippers and so on。
Vinyl elastomer
Properties and characteristics of vinyl elastomers:
The crystalline zone of polyethylene chain (resin phase) acts as the physical cross-linking point，It has typical plastic properties，After adding a certain amount of α-olefin (1-butene, 1-hexene, 1-octene, etc.)，The crystallization zone of the polyethylene chain is weakened，Formed an amorphous zone (rubber phase) showing rubber elasticity，So that the product has the properties of elastomer;POE has the dual characteristics of plastic and rubber with excellent comprehensive performance，Therefore, POE can be regarded as a bridge product of plastic and rubber。
POE elastomers compared to EPDM，It has the advantages of excellent weld strength, good dispersion, high impact strength and excellent molding ability.Compared to SBR，It has the advantages of good weather resistance, high transparency, low price and low density.Compared to EVA, EMA and EEA，It has the advantages of small density, high transparency, good toughness, good flexibility, etc.Compared with soft PVC，It has the characteristics of no special equipment, low corrosion to equipment, good thermoforming, good plasticity, low density, good low temperature brittleness and good economy。
As a plastic toughening agent, POE elastomer can not only toughen and modify polyolefin plastics compatible with it, but also effectively graft with maleic anhydride, glycidyl acrylate and other monomers by peroxides. The grafts obtained are widely used to toughen nylon, polyester and other engineering plastics。
Polyolefin elastomer POE molecular structure has no unsaturated double bond, has a very narrow molecular weight distribution and short branch chain structure (short branch chain distribution uniform), so it has high elasticity, high strength, high elongation and other excellent physical and mechanical properties and excellent low temperature resistance。
The narrow molecular weight distribution makes the material not flexure during injection and extrusion processing, so the processing performance of POE material is excellent。Due to the saturated structure of the POE macromolecular chain, the molecular structure contains relatively few tertiary carbon atoms, so it has excellent heat aging and ultraviolet resistance。In addition, the long branched chain is effectively introduced into the branched structure of the linear short branched chain of the polymer, which improves the transparency of the material and effectively improves the processing rheology of the polymer。
Applications of vinyl elastomers:
POE can threaten rubber, flexible PVC, EPDM, EPR, EMA, EVA, TPV, SBC and LDPE materials;
Used in different products, such as automotive baffles, flexible conduits, conveyor belts, printing rollers, sports shoes, wire and cable, automotive parts, durable goods, extruded parts, press molds, sealing materials, pipe fittings and fabric coatings, etc.
It can also be used as a low temperature impact modifier to improve the low temperature impact resistance of PP, and can be used as a thermoplastic elastomer in the automotive field。
How much elastomer is vinyl and propylene?
The foreign dependence of China's natural rubber has exceeded 85%;
More than 44 million tons/year of new ethylene capacity is being built with vinyl elastomers as a potentially good downstream;
More than 40 million tons/year of new propylene capacity is being built with this potentially good downstream of propene-based elastomers!
Vinyl, propylene elastomers - related technology development is imminent!
Fluorine/silicon elastomer
Fluorine silicone rubber is composed of fluorine silicon polymer as the main formula, fluorine silicon polymer main chain contains a number of silicone groups (-SI-O -), its non-toxic, high and low temperature resistance!Can be made into thermoplastic elastomer。
Fluororubber - "the king of rubber" : has a high degree of chemical stability, is currently the best of all elastomers;Excellent high temperature resistance, excellent weather aging resistance and ozone resistance, vacuum performance and excellent mechanical properties, etc. - excellent comprehensive performance of elastomer varieties。Several small shortcomings: such as low temperature performance is not good, radiation resistance is also poor。
