Biobased ester polyols offer high performance for flexible foam applications


Azelate ester chemistry is a high-performance alternative for the CASE (coatings, adhesives, sealants and elastomers) market. To meet market demand, Emery Oleochemicals introduced a series of polyols under the EMEROX trade name based on azelaic acid (C9 diacid) technology.

cEmery 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. A recent technical article and conference presentation, for which Emery was awarded the Best Technical Paper in the CASE Renewables Session at the 2017 Polyurethanes Technical Conference, outlined the superior characteristics of Emery's bio-based azelate polyols which are engineered to help formulators achieve both performance and sustainability objectives.
In the paper, the Eco-Friendly Polyols Product & Application Development group compared flexible foam performance properties of EMEROX 14060 with 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 were compared as well. Overall Emerox 14060, theazelate (C9) ethylene glycol polyester polyol, exceeded the performance criteria for typical adipate (C6) diethylene glycol polyester polyols for many applications. This should therefore be considered an attractive renewable alternative.
