Abstract
A low-carbon environmentally-friendly foamer composition is disclosed. The composition includes the following ingredients in mass percentage: 60-98.99% of 1-chloro-3,3,3-trifluoropropene, 1-39.9% of 1,1,1,2,3-pentafluoropropane and 0.01-1% of 1,2,2,3-tetrafluoropropane. The GWP value of the low-carbon environmentally-friendly foamer composition is smaller than the GWP value of a single-medium HFC-245fa. This low-carbon environmentally-friendly foamer composition has the features of environmental protection, excellent foaming performance and little modification of foaming devices, and can reduce the heat conductivity coefficient and overall energy consumption level. Therefore, the low-carbon environmentally-friendly foamer composition is the best choice for high-performance hard insulating foam, and is an ideal choice of future foamer.
