| Abstract: | HFC 245fa is an ideal substitute for CFC blowing agent.By synthesis of the polyether polyol HBL 06 and optimization of PU formulation,some problems of the HFC 245fa blown rigid PU foam such as higher thermal conductivity were solved.The performances of the premixed polyols H Y61 are similar to those based on CFC 11. |
