产品说明

Teflon® FEP 160 fluoropolymer resin is a meltprocessible fluoropolymer resin useful for constructions that require very high stress crack resistance in primaries or jackets.

As shown in Table 1, this resin provides the electrical and mechanical properties needed for low-voltage applications. Teflon® FEP 160 has the lowest melt flow of any Teflon® FEP fluoropolymer resin. This high melt viscosity corresponds to a high molecular weight that is useful for constructions with very thick walls, that require exceptional stress crack resistance, or that experience significant thermal cycling. The low melt flow, however, substantially reduces the rate at which Teflon® FEP 160 can be extruded.

Like all Teflon® fluoropolymer resins, Teflon® FEP 160 offers an excellent combination of properties: chemical inertness, exceptional dielectric properties, heat resistance, toughness, flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes, and weather resistance.
