Formula: FEP
Form: Coil
Material: Fluorinated ethylene propylene (FEP)
CAS Number: 25067-11-2
Commodity: Polymers
Transparency:
Clear/Transparent
The FEP Copolymer Coil is available in a total of 105 variations. A fluorinated ethylene propylene copolymer film, it features excellent chemical resistance and electrical insulating properties. With its low friction surface, FEP film finds use as a non-stick coating and as a high-performance electrical insulator in cables and wiring. The different coil sizes and thicknesses in Goodfellow's FEP Copolymer Coil range allow flexibility for industrial applications needing specific dimensions or properties.
