80/20 Toluenes Diisocyanate Tdi for Foaming Agent
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.

Polyether polyols' major use is in polyurethane foams. Flexible foams are primarily used in cushioning applications such as furniture, bedding and car seats, and in carpet underlay.
Rigid foam's largest consumer is the construction industry where it is mostly used for insulation.
Rigid foam is also used in commercial refrigeration and packaging. Smaller uses for polyether polyols include elastomers, adhesives and sealants, surface coatings and polyurethane fibres.
