| Abstract: | In the replacement of blowing agents in rigid polyurethane foams, the property differences between HCFC-141b and CFC-11 systems, such as adhesion to substrates and viscosity of components and heat insulation, dimensional stability brittleness of the foams, were discussed,.The relevant adjusting and modifying measures were taken. The performance of modified HCFC-141b blown foam and the conventional CFC-11 blown foam were compared. |
