The combined blend polyol is well used in refrigeration and refrigeration equipment for home appliances, food and other industries.
polyurethane rigid foam is the most ideal thermal insulation material for freezing and refrigeration equipment, and can achieve ideal thermal insulation efficiency.
Refrigerators and freezers are electrical appliances commonly used in residential households and in industries such as the food industry. Refrigerators and freezers that use polyurethane rigid foam as the thermal insulation layer have a thin thermal insulation layer. Under the same external dimensions, the effective volume is much larger than that of other materials as the thermal insulation layer, and the weight of the appliance is reduced.
polyurethane rigid foam has high strength and is poured between the shell and lining of the refrigerator to form a whole without "thermal bridge", ensuring excellent overall thermal insulation effect of the refrigerator and freezer. Rigid polyurethane foam body insulation materials are generally used in the interlayer of household electric water heaters, solar water heaters and beer barrels. PU rigid foam is also used to manufacture portable insulated boxes for transporting biological products, medicines and food that need to be kept warm and fresh.
With the development of fishery and meat processing industries, these foods are often processed, quick-frozen, and refrigerated on-site to reduce spoilage and improve resource utilization. The refrigeration rooms and large cold storages of enterprises in the marine fishery, meat and other food processing industries also often use polyurethane foam as insulation materials, and are often assembled with hard foam metal sandwich panels, which is convenient and fast.
