Polyimide -Feb tape

BJ-CF polyimide film is the general Polyimide film that is coated or laminated on one or both sides with Teflon? FEP fluoropolymer. It imparts heat sealability, provides a moisture barrier, and enhances chemical resistance.
 
Applications: require a heat bondable film, or moisture and chemical resistance beyond the capabilities of uncoated polyimide films, such as tubing, heater circuits, heat sealable bags, automotive diaphragms and manifolds, magnetic wire,PTC Insulation 
 
Typical size: BJ-CF616, BJ-CF019, BJ-CF919
