Polyurethane chemicals
Polyurethane is formed when a polyol reacts with an isocyanate — TDI or MDI — in the presence of catalysts, surfactants and other additives. Creston Chem supplies every part of that system, sourced from audited producers and documented to specification.
Our four product lines
Source the polyol, the isocyanate and the additive package from a single, accountable desk — with matched specifications and consistent quality.
Polyether and polyester polyols — the backbone of every polyurethane system.
Explore range → PU — 02Toluene Diisocyanate, including TDI 80/20 for high-volume flexible foam.
Explore range → PU — 03Monomeric, polymeric and prepolymer MDI for rigid foam, insulation and CASE.
Explore range → PU — 04Catalysts, surfactants, blowing agents, flame retardants and colorants.

At its heart, polyurethane is the reaction of a polyol (an alcohol with multiple reactive –OH groups) with a diisocyanate (TDI or MDI). Catalysts control the speed of that reaction, surfactants shape the foam’s cell structure, and blowing agents expand it. Change any one input and you change the firmness, density, resilience or rigidity of the finished material.
