Polyurethane is a type of polymer, or large molecule composed of repeated subunits, that is widely used in many industrial and consumer products due to its versatility and durability. It can be rigid or flexible, and is typically used in various items including foam mattresses, insulation, adhesives, sealants, paint, and varnishes. The material is generally resistant to weather, oils, and solvents, which makes it suitable for many applications. The properties of a polyurethane can vary greatly depending on how it is produced, and can include qualities like elasticity, transparency, and resistance to abrasion, heat, and electricity.
