Kevlar Type 49 Specifications
Kevlar is best known as the material in bullet-proof vests for military and law enforcement. In addition to personal body protection, Dupont's Kevlar 49 provides strength and durability to many adhesives, sealants and numerous automotive parts. Kevlar's added tensile strength stretches across the country in fiber optic cables. Does this Spark an idea?
-
Strength and Tenacity
-
Kevlar 49 has a tensile strength of 435,000 pounds per square inch, and can go as high as 535,000 PSI with epoxy-impregnated strands. Kevlar's tensile strength, a measure of resistance to tearing, approaches titanium.
Adhesives, Sealants and Coatings
-
Dupont claims, "in adhesive, sealant, coating and fiber-reinforced plastic applications, Kevlar provides better viscosity control and lower costs." Kevlar also functions at temperatures from cryogenic to 662 degrees Fahrenheit. Kevlar's characteristics reduce cost, as they are unaffected by processing or aging.
-
Automotive
-
Kevlar comes available as a continuous filament yarn, a shorter fiber version, pulp, and an engineered elastomer. Kevlar's several different product forms fit into several automotive materials, including belts, brake pads, clutches, gaskets, hoses, composites and tires.
Fiber Optics
-
Kevlar's lightweight, small diameter flexibility is used in strengthening fiber optic cables. Superior performance brings fiber-to-the-home (FTTH) technology to people looking for high-bandwidth connectivity. Homes, offices and apartments benefit from Kevlar protected cables.
