What material is santoprene?

Santoprene is a brand of thermoplastic elastomer, which belongs to American AES company. Generally speaking, thermoplastic elastomer is a kind of rubber, but this kind of rubber can be thermoplastic molded repeatedly, and ordinary rubber can only be vulcanized once, but not molded twice. So many parts that need secondary molding and assembly need this material, such as the sealing ring in the ball valve. The main components of this material are ethylene propylene diene monomer (EPDM) and polypropylene (PP). In addition to santoprene, sarlink, a brand owned by DSM in the Netherlands, is also good at making this material. At home, Nanjing Jinling Haupt Polymer Materials Co., Ltd. has also done a good job. The registered trademark is Pacrel, which is much cheaper. It also provides technical support. Interested parties can contact jsjlopta @163.com.
