Areas of application
Polyurethanes (PUR) belong to the most important polymers.
The technical area of application of PUR goes from "PUR soles" to "PUR foam". The main area of application of polyurethane is the use of foam, e.g., for upholstered furniture, mattresses, sponges, winter clothing, coating for carpets, constructional foam for thermal insulation, packing material, etc.
They are also used as paint and adhesives, as thermoplastic plastics for the production of rollers, rolls, and as elastomers and fibers, e.g. as elastane.
