  • Patent number: 11186671
    Abstract: A method of forming a flexible polyurethane foam that passes BS 5852:2006 source V (Crib 5) test. The method includes providing a modified polyisocyanate polyaddition (PIPA) 5 polyol formed by contacting a PIPA polyol dispersion with at least one carboxylic acid having a melting point above zero degree Celsius and present in a carrier solvent. The PIPA polyol dispersion has a polyol liquid phase content of 60 wt. % to 90 wt. % and a solid particle phase content of 10 wt. % to 40 wt. % based on a total weight of the PIPA polyol dispersion. From 10 weight percent (wt. %) to 80 wt. % of the modified PIPA polyol is combined with 90 wt. % to 20 10 wt. % of at least another polyether polyol based on a total weight of a polyol blend of the PIPA polyol and the at least another polyether polyol, where the polyether polyol is formed with propylene oxide and ethylene oxide and has an equivalent weight of 1,000 to 2,000 and a functionality of 3 to 6.

  • Patent number: 11124600
    Abstract: Flexible polyurethane foams are made by reacting a polyether mixture and water with a polyisocyanate. The foams have excellent suite of properties for use in seating applications, as they are supporting, comfortable and resilient foam. A further advantage is these properties can be obtained at isocyanate indices of close to or even greater than 100.
