*Related Introduction*
Perfluoroether rubber was developed by DuPont in 1968. The so-called perfluoro does not mean that the fluorine content is 100%, but it means that all molecular chains are C-F bonds, and there are C-H bonds in fluorine rubber. The characteristics of all perfluoroethers are:
1. Excellent chemical resistance
Kalrez® has the same chemical resistance as PTFE and can withstand more than 1,800 chemical media currently known
2. Outstanding high temperature resistance
According to different grades, the highest long-term temperature resistance is 327℃, and the lowest is -42℃
3. Efficient sealing ability
