Perfluoroether rubber consists of a ternary copolymer of perfluorinated (methyl vinyl) ether, tetrafluoroethylene and crosslinked monomer,  also known as perfluoroether rubber. This material has excellent elasticity and thermal and chemical stability of PTFE. Its working temperature range is wide, long-term working temperature more than -10~315 degrees Celsius, short-term can reach 315 degrees Celsius, even below the brittle temperature, can still maintain a certain degree of plasticity, with hard but not brittle, bendable characteristics.

Standard requirements for high-performance perfluoroelastomer seals

The China International Economic and Technical Cooperation Promotion Association has released a group standard (T/CIET) on high-performance perfluoroelastomer rubber seals. This document specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of high-performance perfluoroelastomer rubber seals (hereinafter referred to as "seals"). This document is applicable to perfluoroelastomer O-ring seals that maintain sealing performance under special chemical media environments and/or extreme temperature conditions.
