Poliüretaani

Poliüretaani, often shortened to PU, is a polymer composed of organic units joined by carbamate links. It is formed by the reaction of an isocyanate with a polyol. The specific properties of polyurethane can vary widely depending on the choice of isocyanate, polyol, and other additives used in its production. This versatility allows polyurethanes to be used in a vast range of applications.

Polyurethanes can be found in flexible foams, which are commonly used in furniture cushioning, mattresses, and automotive seats. They are also manufactured as rigid foams, providing excellent thermal insulation for buildings, refrigerators, and pipelines. In addition to foams, polyurethanes are also used in the production of durable elastomers. These elastomers are found in items such as shoe soles, wheels for skateboards and roller skates, and automotive suspension bushings.

Furthermore, polyurethanes are employed as coatings, adhesives, and sealants due to their excellent resistance to abrasion, chemicals, and weathering. They can be found protecting floors, covering furniture, and bonding various materials together. The chemical structure of polyurethane can be tailored to achieve a desired balance of properties, making it a highly adaptable material in modern manufacturing and construction.
