PREPOLYMER COMPOSITION FOR INSULATING FOAMS |
| 摘要 |
A prepolymer composition for preparing polyurethane insulating foams from pressurized containers consists of a prepolymer component with at least one polyurethane prepolymer containing 4-20 % by weight of NCO groups, and commonly used additives, as well as a propellant gas, with 0.01 to 2% by weight of polybutadiene based on the weight of the prepolymer component.
