MSP Polyols™
MSP Polyols™ are soy polyols produced from soybean oil via a novel one-step process that circumvents oxirane formation. As a result these unique polyols are primary polyols, having less steric-hindrance, lower viscosity, less color and higher reactivity than other soy-based polyols. MSP Polyols™ react with every commercially available type of isocyanate and isocyanate terminated pre-polymer, generating potentially unlimited and diverse applications for these reactants in polyurethane formation. The performance of MSP Polyols™ equals and often exceeds conventional polyols, and their reactivity is higher than that of petroleum-based polyols.MSP Polyols™ enable formulators to produce elastomers, coatings, rigid, flexible and isocyanurate foams using concentrations of bio-based materials of up to 100% that exhibit the physical properties typical of polyurethanes made with industry standard polyols.
