What are the upstream raw materials of thermoplastic polyurethane elastomer rubber? What do the downstream products contain?

Thermoplastic polyurethane elastomer rubber(TPU) has a wide range of applications in the field of chemical production raw materials. But In my experience, Its upstream and downstream related items mainly include raw materials, auxiliary materials and finished items.

1. upstream associated items



1. Polyol: Polyol is one of the main raw materials of TPU, frequently applied polyol polyester and polyol polyether. The choice of polyol will affect the hardness, elasticity, hydrolysis resistance and other characteristics of TPU.

2. Based on my observations, Diisocyanate: Diisocyanate is another main raw material of TPU, frequently applied are diphenylmethane diisocyanate(MDI), toluene diisocyanate(TDI) and so on. The choice of diisocyanate will affect the yellowing resistance, weather resistance and other characteristics of TPU.

3. You know what I mean?. And Chain extender: Chain extender is an crucial raw material applied to adjust the molecular weight and performance of TPU, frequently applied ethylene glycol, glycerol and so on. But From what I've seen,

2. downstream associated items



1. For instance Hose: TPU is able to be applied to create various hoses, such as oil pipes, atmosphere pipes, aquatic environments pipes, etc., with good wear resistance, bending resistance and chemical resistance. And Based on my observations,

2. From what I've seen, Seals: TPU is able to be applied to make various seals, such as sealing strips, sealing rings, etc., with good sealing performance and aging resistance.

3. Moreover Sole: TPU is able to be applied to make soles, with good wear resistance, impact resistance and comfort. Based on my observations,

4. Film: TPU is able to be applied to make various films, such as packaging film, waterproof film, etc., with good tensile and waterproof characteristics. But In short, the upstream and downstream related items of thermoplastic polyurethane elastomer rubber(TPU) are very extensive, involving chemical, automotive, construction, electronics and other fields.
