Polyolefin Elastic Fibers? Polyolefin Elastic Fiber Features

Is polyolefin elastic fiber good? Polyolefin elastic fiber characteristics, polyolefin elastic fiber (DOW XLA fiber) is produced by melt spinning from a polyolefin thermoplastic elastomer. XLA, introduced by Dow Chemical in 2002, is the first commercial polyolefin elastic fiber produced by metallocene catalyst-catalyzed in-situ polymerization of ethylene-octene copolymer (POE) by melt spinning. .

It has good elasticity, 500% elongation at break, high temperature resistance of 220 °C, resistance to chlorine bleaching and strong acid and alkali treatment, and has strong UV degradation resistance. Its production process is relatively simple, the raw material price is lower than that of spandex, and there is almost no pollution in the production process and it is easy to recycle. Polyolefin elastomers have been widely used in recent years due to their excellent properties.
