Where it is used
TDI 80/20 reacts with polyol and water to make flexible foam. Slabstock factories use it for blocks that are cut into mattresses, furniture cushions and other foam products. The amount needed depends on the polyol's OH value, the water level and the index you choose.
What to check on the TDS and certificate of analysis
- NCO content and the 2,4 / 2,6 isomer ratio.
- Acidity and hydrolysable chlorine — they affect reactivity.
- Colour and appearance.
- The certificate of analysis of the delivered batch, so your formula uses the real figures.
Storage and handling
TDI is toxic by inhalation and reacts with moisture. Keep containers closed and dry, store and handle it only as the safety data sheet (SDS) says — including the temperature range, because TDI can crystallise when it gets cold — and use the protective equipment the SDS lists. The SDS of the grade we supply is part of every offer.
How much TDI does my formula need?
Customers and free Explorer accounts on our portal can work it out from their own polyol and water levels, and customers can test the full formula in Foam Lab before pouring. Always test a small box before a production pour. Technical support
