Understanding Polyurethane: Composition and Characteristics

Chemical Structure of Polyurethane

Polyurethane, often referred to as PU, is quite fascinating in its chemical makeup. At its core, it’s created by reacting diisocyanates with polyols or diamines. This reaction forms a polymer chain that gives polyurethane its unique properties. One of the reasons polyurethane is so versatile is because of the flexible polyol macro-chains. These chains have low glass transition temperatures, which means they stay flexible even when it’s cold. This characteristic is crucial in applications where flexibility is needed in varying temperatures.
