POE is high-tech elastolefin fiber made of physically linked, denaturized polyolefin raw materials which is very chemical stable. Its molecular microstructure, mainly by “C-C” and “C-H” single bonds, is as firm as that of hexahedral diamond carbon. It can withstand strong acid and alkali corrosion at room temperature for long time without being damaged. The POE is remarkable strong and stable, not easy to age or break as spandex does.

Performance advantage of POE comes from elastolefin's special molecular structure, not from additional post-processing. Because the advantage is innate characteristics of POE, it is durable and stable.
