A durable and surprising strong fiber, DuPont Kevlar is a composite material invented and manufactured by DuPont in 1965. It combines the excellent traits of high strength and light weight, offering five times the strength of steel, 2.5 times the strength of E-grade glass fiber, and 10 times the strength of aluminum per unit weight, making it considered the strongest fiber in the world. Outstanding Special Properties: 1. High tensile and high tensile strength 2. Low elongation, high modulus, and high tensile strength at break 3. High heat resistance, flame retardant, non-melting, non-combustible, only carbonizes 4. High chemical resistance, high stability, and resistance to creep 5. Low coefficient of thermal expansion 6. Low specific gravity 7. Electrical insulator
