FEP
Flexible fluoropolymer with outstanding chemical resistance and electrical properties
FEP (fluorinated ethylene propylene) is a tough, flexible copolymer of tetrafluoroethylene and hexafluoropropylene. It is often used for flexible tubing and fluid processing equipment when chemical resistance, high purity, and low stiffness are required. FEP has outstanding electrical properties and UV resistance.
FEP FDA Compliant Grade is available.
Tech Tip– FEP is less expensive than PFA, but it has a lower service temperature and somewhat inferior electrical properties.
