Polyurethanes, cellular - Nature
Open Data Verified Data
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.

Polyurethanes, cellular - Preparation Method
Open Data Verified Data
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.

Polyurethanes, cellular - Reference Information
| (IARC) carcinogen classification | 3 (Vol. 19, Sup 7) 1987 |
| Introduction | a class of polymers containing-NHCOO-repeating structural units in the backbone of polyurethane polyurethanes. English abbreviation PU. From the isocyanate (monomer) and hydroxyl compound polymerization. Because of the strong polar carbamate group, insoluble in non-polar groups, has good oil resistance, toughness, wear resistance, aging resistance and adhesion. Materials suitable for a wide temperature range (-50 to 150 °c) can be prepared from different starting materials, including elastomers, thermoplastic resins and thermosetting resins. |
| purpose | used to manufacture various kinds of walking wheels, rubber rollers, rubber rods, rubber plates, sealing elements, etc. Used for wool, silk, finishing of cotton and blended fabrics, knitted wool fabrics, medium-length wool-like fabrics, etc. used for various types of wood, chemical equipment, surface finishing of telecommunications equipment and instruments and various transport tools can be used in the manufacture of plastic products, wear-resistant synthetic rubber products, synthetic fibers, rigid and flexible foam plastic products, adhesives and coatings, etc. used in storage tanks, pipes, cold storage, beer, fermentation tanks, fresh-keeping barrels of thermal insulation and cold insulation, building insulation and waterproof, can also be used for prefabricated polyurethane board used in aviation, railway, construction, sports and other aspects; Used for wooden furniture and metal surface finishing; Used for storage tanks, pipes, cold storage, beer, fermentation tank, the insulation and heat preservation of the fresh-keeping barrel, the insulation and waterproof of the building, can also be used for prefabricated polyurethane plate; Can be used for the manufacture of plastic products, wear-resistant synthetic rubber products, synthetic fiber, hard and soft foam plastic products, adhesives and coatings, etc.; Used for all kinds of wood, chemical equipment, telecommunications equipment and instruments and various transportation tools of the surface coating |
