Thermoplastic Elastomers (TPE.TPE) also have the function and properties of traditional heat-return rubber (soft, elastic, and good touch). It also has the advantages of easy processing, rapid and recyclable use of general thermoplastics. advantage. TPE is a thermoplastic rubber whose function and properties are rubberized. Therefore, some people call it Thermoplastic Rubbers (TPR).
Styrene elastomers (TPS) are processed on PS substrates, including SBS, SIS, SEBS, SEPS, and others. Polyolefin (TPO) is based on PP, PE-based various types of copolymers or modified materials, such as a separate mixed type s-TPO, factory (INPLANT) TPO (I-TPO), dynamic increase * TPV and other three.
1. Syndiotactic 1,2 polybutadiene (RB), trans polyisoprene (TPI) and natural rubber TPE (TPNR).
2. Chlorinated TPE is mainly PVC-based TPE (TPVC) or chlorinated PE.
3. The engineering TPE is poly-urethane (TPU), mainly 1 PU (TPU). 2 polyester type (TPEE). (Polyester Type) such as Hytrel.3 Polyamide System (TPAE) such as PEBAX.4 Fluorine-based TPE and Polyether Type used in shoes industry.
Thermoplastic Polyester Elastomer (TPE) Features Specifications How to Use Thermoplastic Polyester Elastomers (TPE) can be molded into a variety of thermoplastic processing methods such as injection molding, extrusion, blow molding, rotational molding, and melt casting. product. Depending on the processing method and the type of polymer, it can be processed between 177°C and 260°C. All grades have a clear melting point and very good melt stability.
TPE is hydrolyzable and does not react with moisture in the air. It has weak water absorption. In order to perfect the parts, it needs to be dried before use. Although the moisture content is below 0.1%, extrusion and molding processing will not produce. defect.
TPE degrades at high temperatures in the presence of acidic media. Therefore, TPE cannot be combined with acidic additives. The viscosity of TPEE is less sensitive to the shear rate, especially at low shear rates such as extrusion.
Before molding, this product must be dried in a forced air oven at 80 to 110°C for 4 to 6 hours. The back material can be mixed with the new material, but the added amount should not exceed 25%.
Injection molding: material temperature should be higher than the product melting range 5 ~ 15 °C, mold temperature is 20 ~ 50 °C, injection pressure is 60 ~ 100MPa, injection speed is medium and low speed.
Extrusion blow molding: The screw length-to-diameter ratio is preferably 24:1, and the barrel temperature should be 5 to 10°C higher than the product melting range.
Product Shape and Packaging All grades of Thermoplastic Polyester Elastomers (TPE) are cylindrical pellets and are packaged in a moisture-proof inner-composite paper bag with a net weight of 25 kg.
Applications The superior properties of thermoplastic polyester elastomers (TPEs) make them suitable for flexible components that require high mechanical strength and durability, and are mainly used in the following industries:
â– Automotive: CVJ dust cover, steering gear sheath, shock absorber sheath, dust cover, traction coupling cover, remote bellows, engine intake air duct, airbag cover, automobile satellite antenna cable clasp, rear Luggage lock assembly, door lock assembly, door handle seal ring, shock absorber plate, silencer gear, pipe plug, plug, ball head, window glass shock absorption seat, shock absorption chassis, chassis stone-resistant coating and so on.

â– Industrial manufacturing: seals, conveyor belts, elevator ramps, high pressure washers, tape recorder silencing gears, quartz clock silencer gears, and **machine springs.
â– Other consumer products: power tools, sporting goods, daily necessities, plastic alloys (blends and adhesives such as PC\PVC\ABS\PBT\PET and other polar plastic thermoplastic elastomers TPR, TPE is a kind of rubber with high elasticity, high strength , High resilience, has the characteristics of injection molding processing, environmental protection and non-toxic safety, a wide range of hardness, excellent coloring, soft touch, weather resistance, fatigue resistance and temperature resistance, superior processing performance, no need to , can be used to reduce the cost of recycling, both can be injection molding, and PP, PE, PC, PS, ABS and other matrix materials, coating and bonding, can also be individually molded.
Thermoplastic elastomers have not only the processing properties of thermoplastics, but also the physical properties of rubber, which is a combination of the advantages of plastics and rubber. Thermoplastic elastomers are now occupying territory that originally belonged only to rubber. In the past ten years, the rapid development of the electronics, communications, and automotive industries has led to the rapid development of the thermoplastic elastomer market.
Thermoplastic elastomers (TPE) have physical and mechanical properties of the rubber and processability of the thermoplastic. Because it does not need to be heated, general-purpose plastic processing equipment can be used to complete production. This feature shortens the production process of the rubber industry by one-fourth, saves energy consumption by 25% to 40%, and increases the efficiency by 10 to 20 times. This is another material and process technology** for the rubber industry.
Advantages of TPR and TPE 1. It can be processed by general thermoplastic molding machine without special processing equipment.
2. The production efficiency has been greatly improved. It can be directly used in rubber injection molding machine, the time from the original 20min, shortened to less than 1min; due to the required time is very short, it can already be used directly to the extruder *, production efficiency has increased substantially.
3. Easy to recycle and reduce costs. The waste generated during the production process (ejected flash, extruded plastic waste) and the resulting waste products can be directly returned to reuse. Old used TPE products can be recycled after simple regeneration, reduce environmental pollution, and expand the sources of renewable resources.
4. Energy saving. Most of the thermoplastic elastomers do not need to be changed or the time is very short, which can effectively save energy. Taking high-pressure hose production as an example, energy consumption is 188 MJ/kg for rubber and 144 MJ/kg for TPE, which can save energy by more than 25%.
5. The application area is wider. As TPE combines the advantages of rubber and plastic, it opens up new applications for the rubber industry.
6. Can be used for plastics to enhance, toughening modification. Self-reinforcing, formula simplification, and the influence of the compounding agent on the polymer are small, and the quality and performance are easier to grasp. However, the heat resistance of TPE is not as good as that of rubber. As the temperature rises, the physical properties decrease greatly, and the application range is limited. At the same time, compression deformation, elastic recovery, and durability are comparable to rubbers, and prices are often higher than similar rubbers. Despite this, the advantages of TPE are still very prominent, and various new TPE products have also been continuously developed. As a new energy-saving and environmentally friendly rubber raw material, the development prospects are very promising.
