Perfluoroelastomer (FFKM) is synthesized by the copolymerization of tetrafluoroethylene monomer (TFE, CF2=CF2), perfluoro-methyl vinyl ether (PMVE, CF3OCF=CF2) and cure-site monomer (CSM, Rf-X).
The chemical structural formula is:
Perfluoroelastomer (FFKM) has the following properties compared with other elastomers (rubbers):
- High temperature resistance
- Chemical solvent resistance
- Low permeability
- Plasma etch resistance
- Reliability and long service life
