If TPV we must be very strange, but if I tell you it is a type of TPE thermoplastic elastomer that you certainly dawned, dynamically vulcanized thermoplastic elastomer TPE-V these years gradually began to replace the traditional vulcanized rubber EPDM, and widely used automotive sealing systems (such as car window seals, automotive door seal). TPE-V has an excellent solvent resistance, high temperature performance. Further flexibility, toughness and tear strength similar vulcanized rubber having excellent low temperature flexibility.












TPE-V and EPDM Comparative advantages:








1, can be completely recycled. TPV thermoplastic compared with vulcanized EPDM, can be completely recycled, can help achieve recovery vehicle.




2, the proportion of light from 0.92 to 0.98, while the proportion of EPDM vulcanized rubber in 1.2 to 1.4. TPV meet the needs of the automotive lightweight trend.




3, avoid direct vulcanization process. TPE-V can be used for direct molding process, less production processes, shorten the process, improve production efficiency.





4, less odor. TPE-V material compounding system in VOC and odor control is more superior to vulcanized EPDM, easier to meet the requirements of automobile manufacturers hosts.




Finally, testing and comparison, we can find TPE-V can almost reach EPDM performance. But at 70 ℃ under high temperature compression set resistance is weak, OEMs need to add water cut in product design, the thickness of the glass run channel lips, helping TPE-V sealing strip does not collapse in the long-term use, no distortion, thereby reducing loss noise performance waterproof and dustproof seal strips
