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 auxiliary 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.
