FLAME RETARDANT POLYURETHANE FOAM AND METHOD FOR PRODUCING SAME |
摘要 |
A polyurethane foam having an initial UL 94 vertical flame classification of V-0 and maintaining a UL 94 vertical flame classification of V-0 after one week of heat aging at 150° C. is formed as the reaction product of an isocyanate component and an isocyanate-reactive component in the presence of a blowing agent. The isocyanate component includes an isocyanate-containing compound and a non-reactive phosphorous compound that is present in an amount ranging from 1 to 20 weight percent based on the total weight of the polyurethane foam. The isocyanate-reactive component includes a polyether polyol and expandable graphite that is present in an amount ranging from 3 to 30 weight percent based on the total weight of the polyurethane foam. |
