TPE (Thermoplastic Elastomer) is a kind of rubber high elasticity, high strength, high elasticity, but also has the characteristics of injection molding material. Environmentally friendly non-toxic safe, wide range of hardness, has excellent coloring, soft touch, weather resistance, fatigue resistance and temperature resistance, excellent processing performance, not curing, can be recycled to reduce costs, both second injection molding, and PP, PE, PC, PS, ABS and other substrate coated with an adhesive, may be formed separately.
The thermoplastic elastomer has both thermoplastic processing performance, but also has the physical properties of vulcanized rubber, it can be described as a combination of plastic and rubber advantages advantages. Thermoplastic elastomers are wantonly originally occupied territory belongs only to the vulcanized rubber.
TPE (Tetraphenylene) is a classic AIE (Aggregation Induced Emission AIE) molecules, ie no fluorescence in solution, but solid, but there is a strong fluorescence quencher molecule with traditional gathering is just the opposite, so organic optoelectronic materials and other areas have important applications, but also more and more cause for concern.

 
TPE
TPE manufacturer
With the rapid development of the domestic economy, we began to have more and more international companies to set up factories in China producing TPE.
In 2012, Sweden HEXPOL Group ELASTO company expects in the second half of 2012, it opened its first production line in Foshan TPE.
In 2010, the United States acquired the former American GLS POLYONE business, including GLS factory in Suzhou.
The rapid development of the automotive industry led to the rapid development of thermoplastic elastomers market.
Thermoplastic elastomer (TPE) having physical and mechanical properties of vulcanized rubber and thermoplastic processing technology performance. Because without heat curing, using a common plastic processing equipment to complete production. This feature makes the rubber industry production processes to shorten the 1/4, energy savings of 25% to 40% and improve efficiency 10 times to 20 times, again material called the Rubber Industry and technology revolution.
This year with the domestic exchanges with the international increasingly frequent, some domestic TPE \ TPR manufacturers have begun toward the development of this flame retardant, which for China and the world have played a more profound impact.
Edit the advantages of this paragraph tpe
1. Generally available thermoplastic molding machining, does not require special processing equipment.
2. The substantial increase in production efficiency. Directly vulcanized rubber injection molding machine, time from about 20min, shortened to less than 1min; need curing time is very short, and therefore already available extruder direct vulcanization, a substantial increase in production efficiency.
3. easy to recycle and reduce costs. Waste generated in the production process (escape flash, out of waste plastic) and eventually scrap can be directly reused return; used TPE old products can simply regenerate after recycling, reduce environmental pollution, expanding sources of renewable resources.
4. energy saving. The thermoplastic elastomer or sulfurized mostly does not require a very short time, can effectively save energy. High pressure hose production energy as an example: rubber 188MJ / kg, TPE is 144MJ / kg, more than 25% energy savings.
5. wider application areas. TPE combines the advantages of rubber and plastic, rubber industry has opened up new fields of application.
6. Can be used to enhance, toughening modified plastics. Since the reinforcement of large, simplified formula, the impact with the agent constraints on the polymer is small, the quality of performance easier to grasp. But TPE heat resistance than rubber, as the temperature rises and properties decreased greatly, and thus the scope is limited. At the same time, compression, elastic recovery and durability equivalent to rubber compared to the poor, the prices are often higher than similar rubber. Nevertheless, the advantages of TPE is still very prominent, a variety of new TPE products are constantly developed. As an energy saving of rubber new materials, the development is very promising.

1. Styrenic TPE
Styrenic TPE also known as TPS, butadiene, or isoprene and styrene block copolymer type, its performance is closest SBR rubber. TPS is currently the world's output reached more than 70 million t, accounting for about half of all TPE. Representative species is styrene-butadiene-styrene block copolymer (SBS), is widely used in the footwear industry, it has largely replaced the rubber; while the tape, rubber and other industrial rubber products in use is also In expanding. SBS is also widely used as impact modifiers PS plastic, asphalt pavement is asphalt paving of wear, cracking, anti-skid excellent soft modifier. PS with SBS modified plastics, not only can greatly improve like rubber as impact resistance, and transparency is also very good. In SBS modified asphalt pavement than SBR rubber, WRP powder, more easily dissolved in the asphalt. Thus, while more expensive, still get a lot of use. Today, more waterproof membrane further extended to the roof of a building, subway, tunnels, trenches and other waterproof, moisture above. SBS and S-SBR, NP rubber and sponge manufacturing, than the original PVC, EVA plastic sponge rubber feel more full, and the ratio of vulcanized rubber to light, bright colors, a clear pattern. Thus, not only suitable for making shoes in the bottom of the sponge, but also shoes, disposable outsole ideal material for sports shoes, fashion shoes and so on.
In recent years, replace isoprene styrene butadiene block polymer (SIS) has developed rapidly, its production accounts for about 1/3 of the amount of TPS, about 90% is used in adhesives aspect. Hot Melt made with SIS not only excellent viscosity and heat resistance Ye Hao, has become a major hot melt material United States and Europe countries. SBS and SIS biggest problem is not the heat, temperature generally can not exceed 80 ℃. At the same time, the strength and elongation, weather resistance, oil resistance, abrasion resistance, also can not be compared with rubber. To this end, the US and Europe and other countries in recent years, it conducted a series of performance improvements, has appeared in SBS and SIS with saturated hydrogenated SEBS and SEPS. SEBS (hydrogenated BR for the soft segment) and SEPS (with IR hydrogenation as soft segments) can greatly improve the impact strength, weather resistance and heat aging resistance or. Japan's Mitsubishi Chemical in 1984 again SEBS, SEPS as the base material made of a mixture of better performance, and this saturated TPS named "Rubberron" listing. Therefore, SEBS and SEPS is not only common, but also engineering plastics to improve weather resistance, abrasion resistance and heat aging resistance of blends, and therefore quickly developed into nylon (PA), polycarbonate (PC) and other projects with plastic "alloy" of the compatibilizer. In addition, also developed many new varieties of epoxy resin with high transparency TPS and use of bio-medical and other non-toxic and TPS.
SBS or SEBS and PP plastic melt blending, etc., may also be formed IPN type TPS. The so-called IPN, is actually two together interpenetrating polymer network, it is also known as IPN compound. While most of them belong to thermoset resins, but there are many like to cross the continuous phase morphology manifested in the thermoplastic elastomer TPE. With SBS or SES as IPN-TPS substrate formed with other engineering plastics can be coated without pretreatment directly. Coating difficult to scratch, and has a certain degree of oil resistance, elastic modulus does not change over a wide temperature range of a low temperature; cold and greatly improving the heat resistance of engineering plastics. Styrenic compounds graft copolymerized with the rubber can become a thermoplastic TPE, have been developed EPDM / styrene, BR / styrene, CI-IIR / styrene, NP / styrene and the like.
2. Olefin-based TPE
Olefin-based TPE with PP as hard segment and EPDM blends for the soft segment, referred to TPO. Because it is lighter than the proportion of other TPE (only O.88), heat resistance up to 100 ℃, weather resistance and ozone resistance Ye Hao, and thus become the rapid development of TPE in another species. Since 1972 the company made UniroyaI TPR tradename listed first in the United States, for many years with double-digit growth in 2000 production reached 35 million t, the 2002 is estimated to be 400,000 t. Now, TPO has become the main rubber material United States and Japan in the field of automobiles and home appliances. Especially in the car have been accounted for three-quarters of its total, with its manufacture of car bumpers, it has basically replaced the original metal and PU. In 1973 there has been a dynamic part of the vulcanized TPO, especially after the 1981 US Mansanto company successfully developed to Santoprere named fully dynamic vulcanization type of TPO, the performance has greatly improved, the maximum temperature up to 120 ℃. This dynamic vulcanization type of TPO referred to as TPV, mainly on the TPO PP and EPDM mixture during melt blending, added cross-linking agent can cure it, the use of mixer, screw machine and other mechanical shear height force, the fine particles of crosslinked rubber EPDM fully cured fully dispersed in the PP matrix being. By this crosslinked rubber "particle effects", resulting TPO's resistance to deformation resistance, heat aging resistance, oil resistance and so has been significantly improved, and even reached the level of CR rubber, so people turn called thermoplastic vulcanizates plastic.
3. Diene TPE
TPE diene isomers mainly natural rubber, it is also known as the thermoplastic trans natural rubber (1-NR). As early as 400 years ago, as a natural rubber that is found in this material, but because produced in the different gutta Hevea and Balata and other wild trees, which is called gutta rubber, Pakistan Lata rubber. This T-NR is used as submarine cables and golf leather etc. Although there are more than 100 years of history, but was a thermoplastic state, crystalline strong, limited availability, it failed to extend long-term use.
Synthesis of T-NR- trans-polyisoprene rubber is made of an organic metal catalyst, called TPI. Its microscopic structure with isoprene rubber (IR) is just the opposite, trans combined 99%, 40% crystallinity, melting point 67 ℃, with naturally occurring and Balata rubber gutta very similar. So, we have begun to gradually replace natural products, and the further development of the orthopedic appliance, plaster substitutes and exercise equipment for protection. In recent years, the use of TPI excellent crystallinity and temperature sensitivity, but also successfully developed a shape-memory rubber material, much people favor.
Structurally, TPI is a crystalline hard segment as high trans structure formed, and then a soft segment portion of the elastic phase state bonding thermoplastic rubber constituted an arbitrary shape and the rest were. Other than the TPE, the advantage of mechanical strength, scratch resistance is good, but also curing, the disadvantage is the softening temperature is very low, generally only 40-70 ℃, use is limited. BR rubber (cis-1,4-polybutadiene a) of the isomers - room with l, 2 polybutadiene, referred to TPB. It is containing more than 90% l, 2-bonded syndiotactic polybutadiene rubber, tradename RB. Microstructure-based block polymer composed of a soft part of each other between the hard segments of any shape with the crystalline portion of the soft segment structure. Although its heat resistance, mechanical strength than rubber, but with good transparency, weather resistance and electrical insulating properties and photolysis, widely used in footwear, sponges, optical films and other industrial rubber products, and other aspects.
TPB Lee TPI lies the biggest difference with other TPE can be cured. TPE can not be used to solve the general sulfur, peroxide curing. But we must use the electronic wave, radiation, and other special equipment only. Can be modified to mention quality problems, thus improving the TPE heat resistance, oil resistance and durability of the poor and other shortcomings. TPB can be arbitrary processing in the melting point of the range of 75-1 10 ℃, both for the production of non-vulcanized injection molding slippers, sandals, vulcanized foam can also manufacture sports shoes, sneakers, etc. in the end. It compared with EVA foam midsole easy to collapse deformation, wear comfortable, help to improve athletic results. TPB film made with good breathability, water resistance and transparency, easy photolysis, very safe, is particularly suitable for families and vegetables, fresh fruit packaging purposes.
4. Vinyl chloride-based TPE
Into a thermoplastic PVC and thermoplastic CPE two categories, the former is called TPVC, the latter known as TCPE. TPVC mainly of flexible PVC modified material, is divided into chemical polymerization and mechanical blending two forms. Mechanical blending mainly a blend of partially crosslinked NBR formed mixed with PVC (PVC / NBR). TPVC actually said to merely extensions of soft PVC resin, but because compression has been greatly improved, thereby forming a rubber-like PVC. This can be regarded as a substitute for PVC TPVC modified products and rubber, mainly used for manufacturing hoses, rubber, tape and some plastic parts. Currently more than 70% of consumption in the automotive sector, such as the car steering wheel, wipers bars and so on. Other uses, wire and about 75%, building waterproof film accounted for about 10%. In recent years, they began to be extended to household appliances, gardening, industrial and other aspects of daily operations raincoat.
5. Polyurethane-based TPE
TPE-based polyurethanes by the urethane hard segments and soft polyester or polyether segments react with isocyanates mutually block bonding thermoplastic polyurethane rubber, referred to as TPU, TPU has excellent mechanical strength, abrasion resistance, oil resistance and flex, especially the most prominent wear. The disadvantage is that the heat resistance, hot water resistance, poor compression resistance, appearance and easy to turn yellow, viscous mold processing is easy. Currently in Europe and other countries is mainly used in the manufacture of ski boots, hiking boots and other sporting goods, and for the production of a large number of various sports shoes, sneakers, consumption of many. TPU also produce automobiles, machinery and watches parts by injection molding and extrusion molding methods, and used extensively for high pressure hoses (rubber outside), pure hose, sheets, belts, conveyor belts, wire and cable, tape and other products. Which accounted for more than 40 percent of injection molding, extrusion molding is about 35%.
In recent years, in order to improve performance craft plus 7 working TPU, but also the emergence of many new varieties of easy processing. As suitable for two-color molding, to increase transparency and high flow, high recovery can improve the processing efficiency of footwear TPU. For the manufacture of non-transparent plastic hose, low hardness and easy processing TPU. For large components such as car bumpers dedicated to glass fiber reinforced to improve the rigidity and impact resistance of reinforced TPU and so on. Especially in the TPU component added to the reaction, after thermoforming, through aging, and the formation of incomplete IPN (crosslinked polymer and non-crosslinked polymer formed IPN) developed very quickly. This IPN TPU further improved physical and mechanical properties of the TPU. In addition, TPU / PC blend type of alloy type TPU, but also improve the safety performance of the car bumper. In addition, high moisture permeability TPU, conductive TPU, and there has been dedicated to the living body, tape, safety glass and other aspects of TPU.
