DuPont™ Kevlar®

Kevlar® brand fiber is an innovative technology from DuPont that combines high strength with light weight to help dramatically improve the performance of a variety of consumer and industrial products. Groundbreaking research by DuPont scientists in the field of liquid crystalline polymer solutions in 1965 formed the basis for the commercial preparation of the Kevlar® aramid fiber. Lightweight and flexible, Kevlar® has evolved over four decades of innovation to do everything from helping save thousands of lives around the world to helping make safer homes and vehicles to helping land spacecraft on Mars. If it needs to be light, strong, or safe, it needs to be Kevlar®.

Fibers of Kevlar® consist of long molecular chains produced from poly-paraphenylene terephthalamide. The chains are highly oriented with strong interchain bonding, which results in a unique combination of properties.

General properties of Kevlar®:

• High Modulus
• High LASE (Load At Specified Elongation)
• High Tensile Strength at Low Weight
• Low Elongation to Break High Modulus (Structural Rigidity)
• Low Electrical Conductivity
• Low Thermal Shrinkage
• High Toughness (Work-To-Break)
• Excellent Dimensional Stability
• High Cut Resistance
• Flame Resistant, Self-Extinguishing
