The reaction between an isocyanate prepolymer and a polyol in the presence of a blowing agent with an amine as catalyst results in the formation of polyurethane foam. Different types of polyurethane foams like flexible polyurethane foam, rigid polyurethane foam, thermoplastic polyurethane etc. are widely used for a variety of purposes.
Polyurethane foams are mainly used in bedding and carpet underlay, furniture, rigid foam insulation panels, gaskets, electrical potting compounds, durable elastomeric wheels & tires etc. With an increase in its applications, the market demand for PU foams is also increasing.

Polyurethane are recyclable, therefore, old, used or spent polyurethane should be sorted and recycled. we need to bear in mind that it takes more than 100years for polyurethane products to decay. Also, they are not biodegradable. Therefore, recycling is the way forward and in the case of some special polyurethane products such as Hospital wastes and the likes, the wastes should be treated before recycling.
