Toluene diisocyanate (TDI):
TDI is the key isocyanate used to make the polyurethane (PU) foam used in furniture, mattresses and car seats. TDI is also used in adhesives, paints, and nylon 6.

Market Dynamics:
TDI is used to make many materials, but the key markets that impact electronics and biopharma will be new auto sales, ie car seats. When the seat foam is made, HCl is a key co-product for several markets. When new car sales dip, the hydrochloric acid becomes tight, which can impact electronics specifically, but also Biopharma..

Up Stream Materials/Building Blocks:

2,4-diaminotoluene (TDA)

Hydrochloric Acid (HCl, co-product)



Down Stream Materials Consuming Toluene diisocyanate:


Foam (mattresses and seats)

Nylon 6
