DuPont debuted a new version of its famous bulletproof Kevlar fabric called EXO at this year’s US Army Rangers Best Ranger competition at Fort Benning Georgia. According to the company, this is his most significant aramid fiber innovation in over 50 years, offering not only better ballistic protection but also lighter weight, flexibility and improved heat resistance.
When you mention Kevlar, the image of a bulletproof vest might come to mind, but there are many more uses for this material. Its blankets protect the International Space Station from micrometeorites, reinforce the hulls of composite boats, are spun into cords, woven into sails, molded into helmets and fire-resistant clothing, used as an alternative to asbestos, and used from hockey sticks. tennis racket.
No wonder 55 million tonnes are produced worldwide every year under various names.
Technically, Kevlar is an aramid fiber, short for aromatic polyamide. A synthetic polymeric material formed from aromatic rings of six carbon atoms arranged along the fiber axis. Simply put, this makes the end result very strong, abrasion-resistant, heat-resistant, non-conductive, and non-flammable under normal conditions.
DuPont says Kevlar EXO not only offers best-in-class ballistic protection over previous versions, but it’s also lighter and more flexible, so soft protective vests made from it fit better and are more comfortable to wear. You will be able to It is also heat resistant up to 500 °C (932 °F) and has a long lifespan of 5 years without significant performance degradation.
said Steven Laganke, global business leader, DuPont Life Protection. “Developed and tested by DuPont’s leading materials experts, Kevlar EXO offers unprecedented ballistic and thermal performance while providing a flexible, lightweight solution that allows users to operate at peak performance. Security or emergency responders, pound by pound, Kevlar EXO users can better manage their energy output, even during the most demanding physical tasks.”
