What is polyurethane

Polyurethane polyurethane, known as polyurethane, is a polymer material. This material is formed by polyol (such as glycerol, butanol, etc.) and polyisocyanate (such as toluene diisocyanate) through a chemical reaction polycondensation, with a thermoplastic linear structure. Polyurethane has good mechanical properties, thermal insulation, sound insulation, anti-virus effect, and anti-seismic effect, so it is widely used in the fields of packaging, sound insulation, filtration materials, elastomers, fibers, surface coatings, and so on. In addition, polyurethane has good elasticity, abrasion resistance, low temperature resistance, high temperature resistance, hardness, and aging resistance, and these properties make polyurethane also have a wide range of applications in the plastics, rubber, medical equipment, industrial, clothing, automotive, aviation, and construction industries. It should be noted that polyurethane may irritate the respiratory tract when inhaled in large quantities, triggering respiratory illnesses or inducing asthma, and should therefore be used with safety in mind
