FEP Resin for Production of Cables with High Cracking Resistance

FEP(Fluorinated Ethylene Propylene) resin is the copolymer of tetrafluoroethylene(TFE) and hexafluoropropylene(HFP),which has good heat stability,excellent electrical insulation, high chemical stability and low friction coefficient. It can be processed by thermoplastic processing method.

Application

The new process and formula of HD926A are adopted to improve the mechanical properties of the product. It is mainly used to prepare cables with high cracking resistance, Robot internal action line, intravenous injection tube and so on.
