Isocyanate is a general term for various esters of isocyanate, used in industries such as home appliances, automobiles, construction, footwear, furniture, adhesives, etc
Monoisocyanates are important intermediates in organic synthesis and are also used to improve the waterproofing of plastics, fabrics, leather, and other materials. Difunctional and above isocyanates can be used to synthesize a series of polyurethane foam plastics, rubber, elastic fibers, coatings, adhesives, synthetic leather, artificial wood, etc. with excellent performance. At present, the most widely used and produced ones are: Toluene diisocyanate (TDI); Methylenephenyl diisocyanate (MDI).
Application:
Used in industries such as home appliances, automobiles, construction, footwear, furniture, adhesives, etc
Nature and Stability
The general term for various esters of isocyanate. There is an isocyanate R-N=C=O and a diisocyanate O=C=N-R-N=C=O. Generally, it is a liquid with an unpleasant odor. Isocyanates are prone to react with ammonia or amines to form ureas, and with alcohols to form carbamates (such as ethyl carbamate).
