Polymers for super strength

SRI’s polymer yarn, circa 1980s

SRI’s patented synthetic polymers, sold commercially by Toyobo Corporation as Zylon®, can be spun into very strong, extremely cut- and heat-resistant yarn that can be woven into fabric. Zylon has a tensile strength that is 1.6 times higher than that of Kevlar.

Applications of the technology include tennis rackets, drive belts for snowmobiles, medical applications, and Formula One racecars. It’s even in some of the Mars exploration rovers.
