摘要： A rigid polyurethane foam includes the reaction product of an isocyanate and an isocyanate reactive component in the presence of a blowing agent. The isocyanate reactive component includes an aromatic polyester polyol, a rigid polyol, and an aliphatic polyester polyol. The rigid polyurethane foam has a tensile adhesion of greater than 35 kPa (5 psi) when disposed on a metal substrate or a polyester, polyurethane, or epoxy coated metal substrate, each having a substrate temperature of greater than 41° C. (105° F.), and tested in accordance with ASTM D1623-09. A method of forming a composite article comprising a substrate and the rigid polyurethane foam includes the steps of combining the isocyanate reactive component and the isocyanate in the presence of the blowing agent to form a reaction mixture and applying the reaction mixture to the substrate having a substrate temperature of greater than 41° C. (105° F.) to form the composite article.
