Many polyurethane products – such as polyurethane foams – are made by combining two types of monomer units namely isocyanates and polyols: MDI (diphenylmethane diisocyanate) or TDI (toluene diisocyanate) depending on the application, and polyether polyols.   MDI isocyanate products are well suited for many industrial, manufacturing, and specialty end-use applications. These applications include appliances requiring insulation like refrigerators and freezers, automotive interior trim and seating; vehicle suspensions and chassis building materials, decorative molding, industrial products, carpet backing, coatings, adhesives, binders, packaging, structural foam, pour-in-place insulation, laminated panel cores, furniture, boats, shoes, and athletic equipment.  Modified MDI is commonly used in the manufacture of the following types of polyurethane foams as rigid and semi-rigid, elastomers, flexible, coatings, integral skin, adhesives, microcellular and binders
