WILMINGTON, Del.—Piedmont Chemical has launched renewable polyester polyols made using Susterra propane diol from DuPont Tate & Lyle Bio Products with bio-succinic acid from Myriant Corp.
Piedmont claims this combination produces high-purity, 100 percent bio-based polyols, "functionally equal and cost-competitive with petroleum-derived polyols," but without "green-price premiums."
Polyols are building-blocks in the production of urethane foams, coatings, adhesives and sealants.
The novel polyols, made from renewable resources, ultimately enable the production of eco-friendly, sustainable products, according to Piedmont. Polyol samples will be available by year-end for urethane producers looking to utilize "green polyols" for their end-market applications, the company said.
