产品说明

TEFLON® FEP 100 fluorocarbon resin is a meltprocessible fluorocarbon resin suitable for extrusion as a primary coating onto most gauge wires (AWG #12 and smaller) for twisted-pair constructions and for limited jacketing applications.

This resin provides the electrical and mechanical properties needed for low voltage applications. TEFLON FEP 100 has a melt flow rate that is between TEFLON 3100 and TEFLON FEP 140. This permits a good combination of extrusion speed and stress crack resistance, making TEFLON FEP 100 the insulation of choice for most primary insulation that is more than 7 mils thick.

TEFLON FEP 100 possesses a balance of processing and performance properties which make it the preferred resin for many applications. Like all TEFLON fluorocarbon resins, TEFLON FEP 100 offers an excellent combination of properties: chemical inertness, exceptional dielectric properties, heat resistance, toughness, flexibility, low coefficient of friction, nonstick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes, and weather resistance.
