What Is Polyurethane?

Polyurethane, often abbreviated as PUR and PU, encompasses a category of polymers consisting of interconnected organic units through carbamate (urethane) links. Unlike typical polymers like polyethylene and polystyrene, polyurethane originates from a diverse range of initial materials.

This chemical diversity gives rise to varied polyurethane structures, resulting in a multitude of applications. These applications span from rigid and flexible foams to coatings, adhesives, electrical potting compounds, as well as fibers like spandex and polyurethane laminate (PUL).

Polyols, isocyanates, catalysts, and silicones constitute systems resulting from the amalgamation or reaction of multiple chemicals, including specialized auxiliary additives.

During the early 1900s, knowledge about synthetic polymers, as we comprehend them today, was limited. Subsequent years witnessed an explosive surge in polymer science, marked by groundbreaking discoveries like polyvinyl chloride (PVC, 1913), polyethylene (1933), polyvinylidene chloride (Saran, 1933), polyamides (nylon, 1934), and polytetrafluoroethylene (Teflon, 1938). Additionally, the 1930s saw the emergence of polyurethanes, a prominent polymer family. Naturally, both polyurethanes and the entire spectrum of polymers developed during this era have seamlessly integrated into modern life.

Given its nature as a technical chemical, this product remains open to continuous research and technological advancement. Undoubtedly, its application is poised to augment further in our daily existence in the times ahead. Notably, foams stand out as the most significant application, accounting for 67% of total polyurethane production in 2016.
