    摘要: A highly temperature resistant foam useful for insulating is disclosed. The foam is particularly useful for insulating stem pipes, hot water heaters and refinery and chemical processing plant pipes. The foam insulation utilizes a cross-linking agent comprised of melamine, which may be dissolved in an alcoholic base. The foam may also include an aromatic polyester polyol, a chlorinated polyester polyol, a nonyl phenol ethoxylate, a silicone based surfactant, and isocyanurate catalyst, a density controlling agent and polymeric isocyanate.The foam will stand consistent temperatures as high as 400.degree. F. It is suitable for spray or poured applications and may be frothed during application.

    摘要: A polymer casting formulation for producing molded polymeric structural members comprises a liquid mixture that contains a polyisocyanate component comprising at least two polyisocyanates; and an isocyanate-reactive component comprising at least two isocyanate-reactive compounds, which formulation cures to form a polyurethane. Methods of using the casting formulation to produce molded polymer structural members and the structural members that are produced by such a method are also described.
