DuPont™ Kevlar® 49 Aramid Fiber
Categories:	Other Engineering Material; Composite Fibers; Polymer; Thermoset; Aramid
Material Notes:	1140 Denier; 768 Filaments. Kevlar® 49 is a high-modulus type used primarily in fiber optic cable, textile processing, plastic reinforcement, ropes, cables, and composites for marine sporting goods and aerospace applications. General KEVLAR Information: DuPont Kevlar® poly-para-phenylene terephthalamide (aramid) has a unique combination of high strength, high modulus, toughness, and thermal stability. It was developed for demanding industrial and advanced-technology applications. It is chemically stable under a wide variety of exposure conditions; however, certain strong aqueous acids, bases, and sodium hypochlorite can cause degradation, particularly over long periods of time and at elevated temperatures.
