Knowing safety is something you can't take for granted, DuPont scientists engineered the superior cut protection of Kevlar. Unlike nylon, polyester and polyethylene, gloves, mittens and sleeves made of Kevlar fiber are Inherently flame-resistant so they won't burn, support combustion or melt - making them a smart choice for those who encounter high levels of heat on the job. The Kevlar fibers produced there are lightweight yarns which will allow manufacturers to make gloves that are even lighter to not only help increase worker safety through more frequent use, but also help improve dexterity and comfort for the wearer.
