ECOTRION是韓國SK化工公司研發(fā)的PO3G（聚三亞甲基醚二醇）的品牌商標，它是SK化工公司所生產(chǎn)的生物基材料旗艦產(chǎn)品之一。ECOTRION，100%來源于可再生的自然生物資源，作為原材料被用于合成需要有柔軟觸感和耐彎曲的材料，如氨綸和PU（聚氨酯）等。相較于石油基的多元醇，ECOTRION所合成的產(chǎn)品具有彈性好，回彈性好和耐磨等特性。

ECOTRION, a 100% plant-based polyol, it's one of the flagship bio-based materials from SK chemicals. ECOTRION, made from PO3G (Polytrimethylene Ether Glycol), is derived from natural sources and is used as a raw material for applications requiring softness and flexibility, such as spandex and polyurethane. It offers superior elasticity, elastic recovery, and abrasion resistance compared to petroleum-based polyols.
