Fluorinated Ethylene-Propylene Resin (FEP) is a copolymer of TFE and HFP with good thermal stability, outstanding chemical inertness, good electrical insulation and low friction coefficient. It can be processed by thermoplastic processing method.

Application:

     EW-521 is new product developed in 2015 with new process method and ingredients.With improved physical performance and crack resistance,EW-521 keeps good performance for dielectrical properties.Mainly used for the insulation of high speed and thin wires & cables with high requirement for crack resistance.

Technical Index:
