Description
Product Overview
Para-aramid (poly-p-phenylene terephthalamide) filament yarn is a high-performance fiber featuring ultra-high strength, high modulus, excellent heat resistance, inherent flame retardancy and good chemical stability. It is widely used in protective equipment, ropes and cables, rubber reinforcement, friction materials, composites and other demanding applications.
