Specialty Polymers

This selection of high-performance sealing materials consists of fluoropolymers (FP), fluorinated ethylene propylene (FEP), polyimide (PI), and polychlorotrifluoroethylene (PCTFE). Each material has unique properties that can be applied to address friction, temperature, pressure, and media challenges in sealing applications. PCTFE, for example, has excellent resistance to shrinkage and deformation at very low temperatures, making it extremely effective in cryogenic environments.
