Abstract: 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.
Abstract translation: 形成具有初始UL 94垂直火焰分级V-0并且在150℃热老化一周后保持UL-94垂直火焰分级V-0的聚氨酯泡沫体，作为异氰酸酯组分和 异氰酸酯反应性组分在发泡剂存在下。 异氰酸酯组分包括基于聚氨酯泡沫的总重量的含量为1至20重量％的含异氰酸酯的化合物和非反应性磷化合物。 异氰酸酯反应性组分包括聚醚多元醇和可膨胀石墨，其以基于聚氨酯泡沫的总重量的3至30重量％的量存在。

Abstract: Methods for forming elastomeric polyurethane articles are provided in which an isocyanate component including an isocyanate prepolymer is mixed with an isocyanate-reactive component having a viscosity ranging from 50,000 to 200,000 centipoise as measured by ASTM standard D2196, and wherein is applied as one or more layers onto a surface of a carrier substrate at an application rate ranging from 0.5 to 20 g/sec, with each one of said applied one or more layers independently having a thickness ranging from 0.2 and 10 millimeters and having a total thickness ranging from ranging from 0.2 to 60 millimeters. The applied layers are cured in the absence of added heat via an exothermic reaction to form the elastomeric polyurethane article having an abrasion resistance ranging from 20 to 250 mm3, a hardness ranging from 60 Asker C to 90 Asker C, and a density ranging from 330 and 1000 kg/m3.
