MANUFACTURING RIGID POLYURETHANE FOAM AND COMPOSITION FOR RIGID POLYURETHANE FOAM |
摘要 |
PROBLEM TO BE SOLVED: To provide a method for manufacturing rigid polyurethane foam having improved thermal conductivity and a composition for the rigid polyurethane foam. SOLUTION: In producing a rigid polyurethane foam by use of a composition comprising an aromatic polyisocyanate, a polyol, a foaming agent, a catalyst, a foam controlling agent and other additives, the foaming agent is a blend of cyclopentadiene and water and the polyol contains a polyether polyol obtained by addition polymerization of an alkylene oxide using of o-toluenediamine as an initiator. |
