titleOfInvention |
Method for producing insulating rigid polyurethane foam |
abstract |
The invention relates to at least a) aromatic amine initiated polyoxyalkylene polyether polyols having a hydroxyl number of at least 200 meq of polyol per gram of KOH,n n n b) aliphatic amine initiated polyoxyalkylene polyether polyols having an hydroxyl number of at least 200 meq per KOH of KOH in an amount of up to 10% by weight, based on the weight of the polyol composition andn n n c) cyclopentanen n n It provides a method for producing a polyisocyanate based closed foam type rigid foam prepared by reacting a polyol composition in which cyclopentane is dissolved with an organic isocyanate. The organic isocyanate and polyol compositions are reacted with an isocyanate index of 80 to less than 150, and the foams produced over this isocyanate index have a substantially constant K-factor and are dimensionally stable. |
