Polyurethane is built from two main building blocks — an isocyanate and a polyol — plus additives that tune the reaction and the final product. Ambizent supplies the full system from trusted global producers.
Isocyanates
MDI (Methylene Diphenyl Diisocyanate) — rigid foam insulation, panels, adhesives.
PMDI (Polymeric MDI) — rigid foams, binders, composite boards.
TDI (Toluene Diisocyanate) — flexible foam for furniture, bedding, automotive.
Polyols & additives
We supply polyether and polyester polyols matched to your foam or elastomer system, alongside the additives that make the chemistry work:
Catalysts — amine and tin (e.g. T9, A-series) to control gel and blow.
Silicone surfactants — for stable, uniform cell structure.
Colorants & pigments — consistent colour matching.
Chain extenders & flame retardants — for performance and compliance.
Applications
| Product family | Made with | End uses |
|---|---|---|
| Flexible foam | TDI + polyol | Mattresses, furniture, automotive seating |
| Rigid foam | PMDI + polyol | Insulation panels, cold chain, appliances |
| CASE | MDI/TDI systems | Coatings, adhesives, sealants, elastomers |
Products meet ISO and ASTM standards, and our team can advise on selection, processing and performance optimisation.
