Rigid polyurethane foam, referred to as rigid polyurethane foam or. It is a mixture of two chemical raw materials (raw materials and raw materials), which form a rigid foam through a chemical reaction. Material: organic isocyanate, polyol (polyether polyol), plus blowing agent, catalyst, flame retardant, etc. The polyurethane foaming machine pressurizes and heats it, and sends it to the mixing chamber of the spray gun through the insulation pipeline. Compressed air is sprayed on the surface that needs to be kept warm, and the foam is formed immediately.
Polyurethane has reached its peak in long-term demand growth, and the supply capacity has quickly increased on the stage. Adipic acid, rigid foam polyether, methyl ethyl ketone, through the rapid expansion of the drive, import substitution, and other products have fallen sharply in recent years, and demand in the third quarter The process of falling. The biggest variable is the demand for energy-saving building materials. According to the calculations of CITIC Securities, the construction area of polyurethane exterior wall insulation projects is 100 million square meters, which can attract 10,000 tons of polymerization. The rigid foam polyether polyols are propylene. 10,000 tons, and the current domestic apparent consumption, China’s built stock market is 100 million, and there is an incremental construction market of 100 million cubic meters per year. Industry standards for new energy-saving building materials will be in place, which will drive the large-scale launch of the polyurethane foam market.
