Abstract
The invention pertains to drip retardant flexible polyurethane foams prepared by the reaction of an isocyanate with a polyol resin containing a drip retardant made of either a trialkyl end-capped amine functional silicone polymer or a trialkyl end-capped carbinol functional silicone polymer to effectively prevent the foam from dripping while burning and encourage char formation.
