PREMIX COMPOSITIONS OF POLYOL, BLOWING AGENT AND OPTIONALLY ADDITIVES HAVING IMPROVED STORAGE STABILITY

摘要

Premixes of a polyol suitable for polyurethane or polyisocyanurate foam preparation, 1,1-dichloro-1-fluoroethane and optionally additives and/or auxillary blowing agents which do not require a stabilizer to inhibit reaction between the fluorocarbon and the polyol. These mixtures are useful for polyurethane and polyisocyanurate foam preparation.
