| Abstract: | A self-cmulsifiable polyether polyol with higher hydroxyl number and lower viscosity is introduced. Some CFC-free or CFC-reducing rigid polyurethane foams based on it are prepared,including half-reducing HCFC-141b or CFC-11 system, n-/iso-pentane system,all-water-blown system. Some studies arc being carried on. The results show that the polyether have good compatibility with CFG replacing blowing agents,the premixed systems based on the polyether have good storage stability,the rigid foams have good physical properties. It is concluded that the polyol can be applied in CFC-frce rigid PU foam systems widely. |
