Gantrade’s poly(trimethylene ether) glycols (PO3G) are 100% bio-based, linear high-performance liquid polyether polyols. Under the trade name ECOTRION, PO3G is derived from bio-based 1,3-propanediol, obtained through fermentation of industrial corn. In polyurethanes, they exhibit good hydrolytic stability in wet environments, low temperature flexibility, excellent toughness and abrasion resistance, and good elastic recovery and resiliency. Gantrade can assist our customers in meeting their efforts to build a “green” polyurethane platform.
