Thermoplastic elastomer (TPR) is a kind of raw material widely used in the field of chemical production, and its upstream and downstream related products are numerous. The following describes in detail the upstream and downstream related products of TPR.

upstream products:

1. Styrene thermoplastic elastomers (SBS, SEBS):SBS and SEBS are the main raw materials of TPR. They have excellent weather resistance, aging resistance and impact resistance, and can be used to produce high-performance TPR products.
2. Rubber: Rubber is an important additive for TPR, which can improve the elasticity and resilience of TPR.
3. Plastic: TPR often add some plastic materials, such as PP, PS, etc., to improve its hardness and strength.

downstream products:

1. Shoe material: TPR is widely used in the production of shoe materials, such as soles, uppers, shoelaces, etc. Because of its excellent wear resistance, impact resistance and comfort, it has become an important raw material in the field of shoe materials.
2. Auto parts: TPR can be used to produce auto sealing strips, fenders, bumpers and other accessories, with excellent oil resistance, acid and alkali resistance and anti-aging performance.
3. Wire and cable: TPR has excellent flexibility and low temperature resistance, and can be used to produce sheath and insulation layer of wire and cable.
4. Medical equipment: TPR has the characteristics of non-toxic, tasteless, and corrosion resistance, and can be used to produce medical equipment, such as infusion tubes, breathing masks, etc.

To sum up, TPR's upstream and downstream related products are very extensive, involving shoes, auto parts, wires and cables, medical devices and many other fields. With the continuous development of science and technology, the application field of TPR will continue to expand.
