Polyurethane is a polymer obtained from hydroxyl bases combined with diisocyanates (usually TDI or MDI). Polyurethanes are classified into two groups based on their chemical structure, differentiated by their behaviour in certain temperatures. This separates them into two types: Thermosetting polyurethanes or thermoplastic polyurethanes (depending on whether they degrade before flowing or flow before degrading, respectively).
The most common thermosetting polyurethanes are foams, widely used as thermal insulators and strong foams.
The most common thermoplastic polyurethanes include those used in elastomers, high-performance adhesives and sealants, shoe soles, paints, textile fibres, sealants, packaging, gaskets, preservatives, automotive components, in the construction industry, furniture and many other applications.
