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. Information provided by DuPont. DuPont and Dow have completed their merger but further transactions/spinoffs are planned.
