What is polyurethane?
According to the Alliance for the Polyurethanes Industry (API), Polyurethanes are formed when a polyol reacts with a diisocyanate or a polymeric isocyanate when there are suitable catalysts and additives present. Polyurethane products are thermoset materials, meaning they cannot be continuously melted and reshaped into new products as can be done with thermoplastics. Recycling technology does exist for many polyurethane products. Producing polyurethane parts involves a chemical reaction whereby specific polyols, isocyanates and additives are added together in specific quantities under specific conditions to produce a polyurethane product with the properties required for that application. Many of these components are in liquid form before they are combined and react with one another. Many polyurethane products such as polyurethane foams are made by combining two types of monomer units isocyanates and polyols. You combine these separate monomers to make the polyurethane polymer.

VITEK polyurethane products are made of an exclusively formulated, high quality rigid polyurethane foam. This man-made polymer is formed on our polyurethane production lines from a two component liquid system which is thoroughly mixed at high speed in mixing/pouring machines. Once mixed, it begins to expand within a few minutes into a rigid cellular mass with a thick surface skin. VITEK polyurethane products are formed in moulds inside presses which exert tremendous pressure to constrain the expansion of the polyurethane foam to yield products with high density, great strength, and a smooth, thick surface finish. Polyurethane is not polystyrene (coffee cup material) or poly vinyl chloride (PVC). It is much stronger and denser than the former and has none of the controversial chemical properties of the latter. In addition, unlike polystyrene or PVC, VITEK polyurethane products readily accept any latex or oil-based paint finish and are all supplied with a thorough coating of high quality
