When everyone is full of confidence that China's polyurethane industry has entered a stage of rapid development, we should pay more attention to the future development direction of polyurethane.

The development prospects of vegetable oil polyether polyol

The status quo of polyether industry: The existing production of polyether polyol is mainly based on petroleum downstream products such as propylene oxide and glycerin, which are tight and costly. Expected goal: The use of different renewable natural oils, including flax oil, rapeseed oil, soybean oil and castor oil can replace high-cost crude oil and natural gas raw materials to produce polyether polyol, that is, the vegetable oil polyether polyol, which can be used in the production of a variety of flexible and rigid polyurethane products, mainly used in automobiles, furniture, mattresses and insulation materials. In the next 10-15 years, vegetable oil-based polyol can replace various components of petroleum refining materials for the manufacture of polyurethane foams, elastomers, coatings, adhesives and sealants, etc.

The research progress of non-isocyanate polyurethane
Non-isocyanate polyurethane makes up for the weak bond structure in the conventional polyurethane molecule from the molecular structure, and with the excellent chemical resistance, hydrolysis resistance and permeability resistance. Besides, the toxic polyisocyanate is omitted in the preparation process, and the raw materials used are not moisture-sensitive, which brings convenience to the preservation and construction of raw materials, and there will be no structural defects in the material due to the formation of bubbles. In view of the above reasons, accelerating the research and development of non-isocyanate polyurethane is an important direction for the development of new polymer materials in China. Non-isocyanate polyurethane has a very broad development prospect and is a new generation of polyurethane system.
