polyurethane

 

Polyurethane (PU) is a polymer created by the reaction of polyols (organic compounds with multiple hydroxyl groups) with isocyanates (compounds containing isocyanate groups). This reaction leads to the formation of a dense network of polymer chains that make up the polyurethane material.

Polyurethane is widely used in various industries, including construction, automotive, furniture, packaging and many others. Its thermal insulation properties make it a popular material for thermal insulation.

Thermal insulation is the ability of a material to limit the penetration of heat between two environments with different temperatures. Polyurethane thermal insulation is characterized by high thermal resistance and low thermal conductivity. Heat is hardly transferred through the polyurethane material, which means that the thermal energy is kept inside the insulated space and the lossy heat exchange with the outside environment is minimized.

Polyurethane thermal insulation is often used in construction to insulate walls, roofs, floors and other structures. It is very effective in reducing the penetration of heat through the perimeter envelope of the building and helps to maintain a pleasant temperature in the interior, reduces energy consumption and contributes to savings on heating and cooling.

In addition to thermal insulation, polyurethane also has other advantages, such as high strength, resistance to moisture and chemicals, flexibility and the possibility of creating different shapes. It is available in the form of sandwich panels, foam, sprayed insulation layers and other applications that adapt to the specific needs and requirements of the structure.
