Publication number: 20180282469Abstract: Polyurethane foams are provided. The polyurethane foams are produced from a formulation that includes an isocyanate reacting mixture, an isocyanate component, and a blowing agent. The isocyanate reacting mixture includes at least 40 wt % of at least one propoxylated polyester-polyether polyol based on the total weight of the isocyanate reacting mixture. The isocyanate reacting mixture also includes at least one of propoxylated sucrose polyol or propoxylated sorbitol polyol. The propoxylated sucrose polyol and/or propoxylated sorbitol polyol has a hydroxyl number of from about 300 mg KOH/g to about 600 mg KOH/g. The polyurethane foam has a compressive strength of at least 130 kPa, and a stoichiometric index of the isocyanate component to the isocyanate reacting mixture is between about 1.0 and 1.7.Type: ApplicationFiled: September 19, 2016Publication date: October 4, 2018Applicant: Dow Global Technologies LLCInventors: Paolo GOLINI, Cecilia GIROTTI
