Polyurethane

Polyurethane (PUR) is a synthetic polymer known for its wide range of properties and applications. It is produced by the reaction of polyols with isocyanates, resulting in materials that can vary from foams and elastomers to fibers or rigid plastics. This versatility allows polyurethane to be used across many industrial sectors.

In the construction industry, polyurethane is primarily used for thermal and acoustic insulation, especially in the form of rigid PUR foam. In the furniture and automotive sectors, soft polyurethane foams are used in the production of mattresses, car seats, and cushions. It is also used in flooring systems, gaskets, and protective coatings or paints.

In textiles, polyurethane appears in waterproof coatings on technical fabrics and in elastic fibers such as spandex or elastane. In footwear manufacturing, it is used in midsoles and outsoles due to its elasticity, durability, and lightweight properties.

Polyurethane is resistant to mechanical stress, moisture, and many chemicals. Depending on its formulation, it can be rigid or flexible, soft or hard. Some types of polyurethane can be recycled or used for energy recovery.
