Name ：Toluene diisocyanate, referred to as TDI (Toluene-2,4-diisocyanate)
Molecular formula ：CH3C6H3(NCO)2
Appearance：Pure TDI is colorless to pale yellow liquid, which reacts with water to produce carbon dioxide, soluble in ethanol, acetone and other organic solvents
Uses ：As an important chemical raw material, TDI is widely used in the production of polyurethane foam, polyurethane elastomer (polyurethane rubber), polyurethane coatings, polyurethane paints, polyurethane adhesives, polyurethane waterproof materials and manufacturing detergents, thickeners, anti- Oxygen and modifier products
