FEP is similar to PTFE with regard to excellent dielectric properties; chemical inertness; toughness at low temperatures; low coefficient of friction; non- stick properties & weatherability. FEP has a higher degree of transparency and a greater modulus of elasticity at low temperatures than PTFE. As with all fluoropolymers, FEP tubing can be steam cleaned or chemically sterilized according to all industrial standards & is produced from FDA approved raw material.
