Polyurethanes are a family of polymers produced through a chemical reaction between an isocyanate and a polyol. First developed in late 1930s, polyurethanes are some of the most versatile polymers. They are used in building insulation, surface coatings, adhesives, solid plastics, and athletic apparel. They utilize a broad range of polymer backbones and reactants to produce a family of products ranging from rigid, clear, glass like products to low density resilient foams. MarChem provides a wide range of products based on aromatic and aliphatic polyurethane chemistries. These include both two part polyurethane systems and single component polyurethane prepolymers. Some specific types and end products are shown below.
