Miscible Blends of PTMEG Polyols with Polycaprolactone Polyols

PTMEG are known as high-performance polyols capable of formulating polyurethane elastomers in several positive directions. PTMEG polyols afford polyurethane elastomers with enhanced performance with respect to flexibility, dynamic properties, low-temperature performance, resiliency/rebound, hydrolytic stability, low hysteresis, and abrasion resistance.

Epoxy Resins

Epoxy resins are a highly versatile class of multifunctional reactive intermediates that are crosslinked into three-dimensional networks with curing agents or “hardeners” such as multifunctional amines, carboxylic acid anhydrides, and phenolic resins.  When cured, the resulting thermoset materials are formed without the generation of volatile by-products. This results in void-free cured parts, which is particularly important in thick structures.

Polytrimethylene Ether Glycol (PO3G): 100% Bio-Based Polyol

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.
