METHOD FOR PRODUCING FLEXIBLE POLYURETHANE FOAM

摘要

Disclosed is a method for producing a flexible polyurethane foam with excellent mildew resistance and antibacterial properties wherein a mechanical frothing process is used. The method for producing a flexible polyurethane foam is characterized in that an isocyanate liquid (A) composed of an organic polyisocyanate (a), a polyol liquid (B) wherein a polyol (b1), a catalyst (b2), a foam stabilizer (b3) and colemanite (b4) are mixed in advance, and an inert gas (C) are mixed and dispersed by mechanical stirring and then the resulting mixture is foamed and cured.
