TPV, vulcanized thermoplastic elastomer which is made of PP, EPDM, vulcanizing agent and so on. It combines the characteristics of rubber and plastic with high heat- resistance. The compression deformation is better than that EPR. Meanwhile, TPV has good processing properties and non-toxic materials which can be reused. In recent years, TPV is widely used in sanitary hose, automotive sealing strip etc. TPV hose can be used under the temperature - 40 ~ 110 ℃ in long time. It is significantly better than PEX hose 0 ~ 95 ℃ and PVC tube 5 ~ 45 ℃ and also it has better stability, useful life.
