A full line of natural-oil polyols (NOPs) for polyurethanes will be launched next year by Dow Polyurethanes, Midland, Mich. NOPs can be made from soybeans, sunflower seeds, or rapeseeds, although Dow is initially focusing on a polyol that contains a significant percent of soybean oil. Dow plans to begin market-development production of this polyol in 2007, after a year's small-scale product testing with select customers. Dow says it can produce NOP products that match or exceed the performance of hydrocarbon-based polyols by creating optimized blends of NOPs and standard propylene oxide polyols. Dow addressed earlier performance challenges with NOPs, such as retaining tensile strength, resiliency, and compression set. Dow plans to develop NOP-based products for flexible slabstock, molded foams, and some CASE (coating, adhesive, sealant, elastomer) applications.
