Applications
- Flexible Foam (Mattresses) — Reacts with polyol and water to produce open-cell flexible foam; primary use of TDI 80/20 globally
- Furniture Upholstery — Used with high-reactivity polyols to produce seating foam with defined IFD (hardness) values
- Automotive Foam — Produces moulded seat cushions, headrests, and door liners in automotive applications
- PU Coatings — Used in two-component PU coatings for wood, metal, and plastics; provides excellent hardness and UV stability
- Elastomers — Cast PU elastomers for rollers, wheels, and industrial parts requiring abrasion resistance
- Carpet underlay and foam underlays
- PU coating and lacquer systems
- PU adhesive and sealant production
- Textile backcoating
TDI is a highly reactive isocyanate and a sensitiser — inhalation can cause asthma-like symptoms even at very low concentrations. Mandatory requirements: respiratory protection (supplied-air respirator for high concentrations), chemical-resistant gloves, eye protection, and full-body coverage. Storage in a cool, dry location away from moisture. Refer to the full SDS before handling.
