Although Kevlar's heat resistance is not as
great as that of Nomex, Kevlar's strength is
superior to all other fibers. In fact, Kevlar is
five times stronger than steel by weight. It has
become the thread choice in those special high
stress, volatile applications that require
extreme strength and heat protection.
