Laser Line 200 Lb. tensile strength - Three stranded twisted torque balanced Kevlar® 49 base with proprietarypolyurethane double coating with a low friction finish impregnated into the cord. This is the ultimate cord for use in extreme conditions. Current applications include: Use in mechanical float assemblies in waste oil tanks. Military uses in ocean environments. High performance light weight stunt kites. Target suspension. Kevlar is the registered trademark for a para-aramid synthetic fiber, related to other aramids such as Nomex and Technora. Developed at DuPont in 1965, this high strength material was first commercially used in the early 1970s as a replacement for steel in racing tires. Typically it is spun into ropes or fabric sheets that can be used as such or as an ingredient in composite material components. Currently, Kevlar has many applications, ranging from bicycle tires and racing sails to body armorbecause of its high tensile strength-to-weight ratio; by this measure i
