Product Description
DuPont™ Teflon® FEP CJ-95 is a melt-processible fluoropolymer resin specifically designed for cable insulation and jacketing applications that demand a high degree of stress crack resistance.

This resin provides the electrical and mechanical properties needed for low-voltage applications. Teflon® FEP CJ-95 has a higher melt flow rate than Teflon® FEP 140, but it retains similar stress crack resistance.

Like all Teflon® fluoropolymer resins, Teflon® FEP CJ-95 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.
