Kevlar Protective Materials

Pushing the limits of protection, performance and strength What is Kevlar®? Pushing the limits of protection, performance and strength Created by Stephanie Kwolek, Arclin Kevlar® is a heat-resistant para-aramid synthetic fiber with a molecular structure of many inter-chain bonds that make Kevlar® incredibly strong. Best known for its use in ballistic body armor, Kevlar® also has many other applications because of its high tensile strength-to-weight ratio. Stephanie Kwolek: stronger than steel A pioneer in polymer research, Stephanie Kwolek accumulated several patents and awards throughout her career. Most notably, she is known for her groundbreaking work that led to the creation of Kevlar® - an incredibly strong material that continues to push the limits of possible. Core Properties Tensile strength: The chemical structure of Kevlar® is comprised of several repeating inter-chain bonds. These chains are cross-linked with hydrogen bonds, providing a tensile strength that can be up to 10X stronger than steel on an equal weight basis. (Results may vary as there are multiple types of steel with varying tensile strengths and multiple types of Kevlar® yarn with varying tensile strengths.) Ballistic resistance: Kevlar® fibers are so tightly spun that it is nearly impossible to separate them. When a bullet or other high-velocity projectile hits Kevlar®, the fibers essentially catch the projectile while absorbing and dissipating its energy. Cut & puncture resistance: Due to the fully extended and perfectly aligned molecular chains within Kevlar® fiber, Kevlar® provides a strong protective barrier against slashes, cuts and punctures. Heat resistance: Kevlar® is inherently flame resistant—protecting against thermal hazards up to 800 degrees Fahrenheit. Additionally, Kevlar® fibers won't melt, drip or support combustion. Applications Kevlar® for PPE, Aerospace, Automotive, Consumer Products, Mining, Fiber optics, Life protection, Ropes & cables.
