Emery Oleochemicals, through its Eco-Friendly Polyols platform, offers EMEROX® renewable content polyols for flexible foam applications. EMEROX polyols are produced from dibasic acids that are a product of the company’s proprietary ozonolysis technology. These polyols possess all the structural design freedom of a petrochemical-based polyol, but with a high renewable content and often with superior performance properties.
EMEROX 14060, a bio-based azelate (C9) ethylene glycol polyester polyol developed by Emery Oleochemicals, targets “click-able” flexible ester foams and CASE applications. In a recent technical article, the Eco-Friendly Polyols Product & Application Development group compared flexible foam performance properties of EMEROX 14060 versus an adipate (C6) diethylene glycol polyester polyol in 32 kg/m3 (2 pcf) foam formulations. Foam “click-ability” (i.e. smooth cut as opposed to a pinched foam edge when die cut) and polyol/polyurethane hydrophobicity aspects are compared as well. Overall EMEROX 14060, an azelate (C9) ethylene glycol polyester polyol, exceeds the performance criteria for typical adipate (C6) diethylene glycol polyester polyols for many applications and should be considered an attractive renewable alternative.
PU Magazine International recently published Emery’s Eco-Friendly Polyols technical article in their August/September 2017 issue.
