Polyol-blowing agent compositions with improved storage stability
摘要:
Premixes of a polyol suitable for polyurethane or polyisocyanurate foam preparation and 1,1-dichloro-1-fluoroethane require no stabilizer to inhibit reaction between the fluorocarbon and the polyol. These premixes are useful for polyurethane and polyisocyanurate foam preparation.
