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 made into a wide 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 comes in many different shapes, densities and firmness levels. Polyurethane foams are used in a wide variety of applications, including upholstery, mattresses, cushions, and insulation. PUR foams offer high resistance to abrasion and compression and can also be used as insulation to improve the energy efficiency of buildings.

Polyurethanes are also used as adhesives and coatings because they offer excellent adhesion to a wide variety of surfaces and exhibit 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 manufacture of synthetic leather materials. Polyurethane-based textiles offer excellent abrasion and tear resistance, making them 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.
