Hot sale Toluene Dissocyanate/TDI Toluene diisocyanate (TDI) is an aromatic diisocyanate that is a clear, pale yellow liquid with a sharp, pungent odor, which is insoluble in water and miscible with most common organic solvents. TDI (CAS No. 26471-62-5) consists of two isomers: toluene-2,4-diisocyanate (2,4-TDI) (CAS No. 584- 84-9) and toluene-2,6-diisocyanate (2,6-TDI) (CAS No. 91- 08-7), which is commercially produced in different ratios. The most common ratio is 80% 2,4-TDI/20% 2,6 TDI. TDI is widely used and accounted for 34% of the global isocyanate market in 2000 Tdi 80/20 is used for Flexible Polyurethane Foam and other other polyurethane applications including elastomers,synthetic leather,coated fabrics,paints and adhesives. It is spray-applied,closed-cell polyurethane foam system with high fire resistance properties.it applies to all kinds of spray-applied thermal insulation engineering,such as building exterior cold rooms,large-scale pipeline,etc.
