Product Description

    

Mdipm200 Polyether Polyol Mdi Polyurethane Adhesive Isocyanate Rigid Foam
MDI (diphenylmethane diisocyanate) is an important isocyanate used in the synthesis of polyurethane resins. Its molecular structure contains two benzene rings and has a symmetrical molecular structure. The polyurethane elastomer obtained has good mechanical properties. The reactivity of MDI is greater than that of TDI. The relative molecular mass of MDI is greater than that of TDI, the vapor pressure is very low, the volatility is low, and the toxicity to the human body is relatively small. Pure MDI is mainly used in the manufacture of various polyurethane elastomers, mostly used in the production of thermoplastic polyurethane elastomers, spandex, PU leather slurry, shoe adhesives, and also used in the manufacture of microporous elastomer materials (shoe soles, solid tires, self-skinning foam, car bumpers, interior parts, etc.), cast polyurethane elastomers, etc. Compared with pure 4,4'-MDI, MDI products with high 2,4'-MDI content have lower reactivity and melting point. Due to the difference in reactivity between 2,4'-MDI and 4,4'-MDI, MDI-50 provides better flowability for the production of molded products. This product can be widely used in the production of various polyurethane elastomer products, adhesives, coatings, automotive parts, and interior decoration parts. It can also be used as a substitute for TDI in the production of soft polyurethane foam, which can reduce environmental pollution and improve operating conditions.
  Polyurethane rigid foam is referred to as polyurethane rigid foam, or PU. It is a mixture of two chemical raw materials (material A and material B), which form a rigid foam through chemical reaction. Material A is organic isocyanate, and material B is polyol (polyether polyol) plus foaming agent, catalyst, flame retardant, etc. Material A and material B are pressurized and heated by the foaming machine, sent to the spray gun mixing room through the insulation pipe for mixing, and sprayed on the surface to be insulated with compressed air to instantly foam to form a rigid foam. It can be widely used in cold storage, food factories, chemical plants, industrial buildings, civil buildings, storage tanks and other spray insulation fields. The product has good fluidity, convenient production and operation, uniform and fine pores, and uniform density distribution. It can be constructed on steel plates, cement surfaces, brick surfaces, wood surfaces and other substrates. It has strong adhesion, excellent dimensional stability and thermal insulation.
