The aromatic polyester polyol is used in the CFH-168 raw material of the polyurethane rigid foam composition, which improves the strength and cell fineness of the polyurethane rigid foam, has excellent heat and flame retardant properties, and has good toughness and dimensional stability, all the properties are obviously better than those of pure Polyether polyurethane rigid foam.
The foaming process of semi-rigid foam generally includes semi-prepolymerization and one-step method. In the semi-prepolymerization process, polyether triol and TDI are firstly prepared into prepolymer, and then the low molecular weight polyether with high functionality is used as crosslinking agent, and the water foaming system is used for foaming. The one-step process is based on crude MDI and high molecular weight of high activity Polyether glycol as the main raw material, the crosslinking agent, foaming agent and other mixing foaming and prepared.
Cold insulation materials for refrigerated vehicles, anti-corrosion and thermal insulation materials for oil pipelines, thermal insulation and cold insulation materials for equipment and various pipelines, building structural materials and thermal insulation materials, wings, filling support material of the tail, etc.
