Progress in perfluoropolyether-based elastomers

Abstract

Perfluoropolyether(PFPE)-based elastomers were new elastomers with extremely low glass transition temperature and excellent resistance to polar solvents. The structure and molecular weight of PFPE, the main raw material for preparing PFPE-based elastomers, were briefly introduced. The structures, synthesis methods and properties of three typical elastomers, including PFPE elastomer containing triazine ring, PFPE silicone elastomer and PFPE polyurethane elastomer, were summarized with 26 references. Finally, the development direction and market prospect of PFPE-based elastomers were prospected.
