產品說明

Teflon® FEP 140 fluoropolymer resin is a meltprocessible fluoropolymer resin suitable for extrusion as a primary coating for heavy wire gauges (AWG #11 and larger) and for limited jacketing applications.

This resin provides the electrical and mechanical properties needed for low-voltage applications. Teflon® FEP 140 has a lower flow rate than either Teflon® 3100 or Teflon® FEP 100. This low melt flow corresponds to a high molecular weight that provides significant stress crack resistance for thick-walled constructions. The low melt flow, however, significantly reduces the rate at which Teflon® FEP 140 can be extruded.

Like all Teflon® fluoropolymer resins, Teflon® FEP 140 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.
