Gantrade’s poly(trimethylene ether) glycols (PO3G) are 100% bio-based, linear high-performance liquid polyether polyols. This series of 100% sustainable content polyether polyols was commercialized by SK Chemicals in a newly completed production facility in Ulsan, South Korea. Introduced under the trade name ECOTRION, PO3G is derived from bio-based 1,3-propanediol, obtained through fermentation of industrial (non-food) corn. A ISO 14000 compliant life cycle analysis found that PO3G offers a lower environmental footprint including a 45% reduction in greenhouse gas emissions.
