Product Description
Product Details
Introduction
FEP powder is a modified material of polytetrafluoroethylene, which is a copolymer of tetrafluoroethylene and hexafluoropropylene. The content of hexafluoropropylene is about 15%.
Physical and chemical properties
The molecular weight of FEP is 200000-600000, MFR (372 ℃, 5kg) is 0.8-32g/10min, melting point is 250-275 ℃. FEP has excellent mechanical and electrical properties. The oxygen content required for continuous combustion is 95 vol%, and it has good chemical resistance.
Application
It is mainly used for insulation and sheathing of high-temperature wires and cables, and can also be used as sheathing, insulation, high-temperature and corrosion-resistant pipes and films for large-size data and communication wires, as well as valves, pumps, and pipe linings.
