Companies combine to bring sustainable polyester polyols to the market
03/12/2012
The new products combine Susterra propanediol from DuPont Tate & Lyle (DTL) Bio Products with bio-succinic acid from Myriant Corporation to produce the 100% bio-based polyols. On announcing the development, Piedmont said the new intermediates were “functionally equal and cost-competitive with petroleum-derived polyols without requiring green-price premiums”.
Under a strategic collaboration between Piedmont, DTL and Myriant, the three companies have agreed to an “open innovation” concept by which the polyol formulations will be made available to polyol producers and the urethane industry at large. This means that polyol customers will be able to purchase polyols produced from DTL’s Susterra propanediol and Myriant’s bio-succinic acid from Piedmont as well as from other polyol producers. Piedmont will manufacture the initial polyol product samples and will offer commercial supply of the polyol products to the market.
“We have worked with Myriant’s and DTL’s products for some time now. In deciding on suppliers and collaboration partners it was critical for us to be certain that these renewable chemical building blocks would be available at commercial quantities with the right specification. In the last year, we have become confident that both Myriant and DTL meet these requirements,” said Emil Delgado, chief operating officer for Piedmont.
