TPEApplication

1. Footwear
Injection mol soles and combine soles ( a simple combination of heel and sole ) are primarily used to make common shoes and athletic shoe. these materials provide traction, low temperature flexibility, fatigue resistance, and wear resistance of the shoe.
2. Wires and cables
They also have good resiliency and low temperature flexibility, comparable to cross-linked PE, vulcanized rubber and PVC, and are competitive in automotive main circuit conductors, equipment conductors, flexible ropes, booster cables, and trailer cables. Styrene tpes also has other important properties for wires and cables, such as strength, wear resistance, rolling resistance, impact resistance, fire resistance, thermal stability, dielectric properties, etc. most conductors and cables are constructed to ul standards, SAE and other major industry standards.
the TPE parts with light weight are used to replace the rubber and metal parts on the automobile, which can not only maintain the corresponding performance, but also reduce the manufacturing cost and improve the fuel efficiency of the automobile. For these applications, the best material is a styrene block copolymer, because applications under the hood of an automobile require a higher temperature of use, as well as low temperature flexibility and ozone resistance. Some special applications require grades of tensile strength of 24.1 MPa to produce heating and air conditioning ducts. Gaskets, sealing rings, etc. The parts to be decorated can also be painted and hot stamped.
3. Biomedical applications
Medical devices made from styrene tpes have superior performance over rubber products because they do not have residues like rubber vulcanization. An effective method of sterilizing these products may be ethylene oxide, radiation, steam. Polysiloxane - modified styrene block copolymers have been widely used as materials for the manufacture of medical devices. these newly born materials improve tensile residual deformation and transparency. and is a silicone rubber. PVC, TPU, TPO and other useful substitutes for styrene tpes products used in the medical device industry. The styrene TPE material prepared for biomedical application has wide performance, excellent biocompatibility, variable hardness range, good resilience, low tensile residual deformation and compression residual deformation, and temperature stability. these materials are used as urinary implants, medical tubes. Medical sheet and film, ball tube, medical sealing ring, gasket and diaphragm, etc. In addition, these tpes can be used to make surgical drapes, medical films, baby bottles, transparent nipples, dispensing tubes, etc. Within the application areas specified by the food and drug administration ( FDA ).
4, adhesive, sealant, coating, packing
Styrene tpes can be made into high strength elastic materials and films, they have become a very important category, can be used to formulate sealants and coatings, the greatest advantage is to be able to attach to a variety of materials. They can also be used as roof coatings, can sealants, strippable coatings, and to improve the performance of rubber-based adhesives and sealants. Their uses also include assembly adhesives, pressure sensitive adhesive tapes, labels, packaging adhesives, and building adhesives.
5. Impact modification
Even if very small amounts of styrenic tpes are added to PS, PE, PC, and PP resins, the toughness, impact strength, and flexural properties of these materials can be effectively improved. this modification of the material also improves the resiliency of the biaxially oriented PS without much loss in transparency of the resulting thermoformed sheet film. Styrenic tpes have been shown to improve the impact strength and tear strength of HDPE and LDPE blown films. Injection molded products of PP and styrene TPE blends have relatively high low temperature impact strength. Such as the addition of styrenic tpes to certain resin recovery materials, can improve the performance of these materials.
6. Asphalt
A small amount of styrene TPE was used to modify asphalt, which improved the low temperature flexibility, elongation and fatigue resistance of asphalt. this modified material has been used as roof material, pipe coating, tank lining, sealing layer.
7. Compatilizer
Because of their compatibility with many resins, styrenic tpes can sometimes be used as compatibilisers in the formation of alloys from two or more generally incompatible polymers.
