Fluorinated Ethylene-propylene (FEP) Film
FEP film is made from FEP resin and prepared by extrusion blowing technology. It can be used at the temperature range of -80℃ through 200℃. There are two types of products: general-purpose FEP film and electric-purpose FEP film. Electric–purpose FEP film has excellent electrical property and is used as dielectric material for capacitor, flexible PCB and flat cable etc. General – purpose FEP film has outstanding chemical resistance to virtually all chemicals and is used as a transparent, anti-corrosive and anti-stick material in the fields of chemical, food, textile and packing industries. These films conform to the enterprise standard of Q/GHAD 11-2005.
