PUR / PU
Polyurethane (PUR) is an extremely versatile plastic that is used in many applications. It is made by reacting a polyol and an isocyanate together, creating a polymer that can be produced in a variety of shapes and properties. The properties of polyurethanes can vary from soft and flexible to hard and brittle, depending on the materials used and the specific manufacturing conditions. One of the most common uses of PUR is as a foam, which is available in many different shapes, densities and strengths. Polyurethane foams are used in a variety of applications, including upholstered furniture, mattresses, cushions and insulation. PUR foams offer high resistance to abrasion and compression and can also be used as insulating materials to improve the energy efficiency of buildings. Polyurethanes are also used as adhesives and coatings as they offer excellent adhesion to a wide range of surfaces and have high resistance to chemicals and abrasion. Polyurethane coatings offer excellent durability and corrosion resistance and are often used in the automotive and construction industries.In addition, polyurethanes are also used in fibers and textiles, such as in the production of synthetic leather materials. Polyurethane-based textiles offer excellent resistance to wear and tear and are therefore ideal for applications such as workwear and protective clothing. Overall, polyurethanes are an important plastic that is used in many different applications due to its versatility and excellent properties.
