Polyurethane in construction
Polyurethane (PUR or PU) is a polymer formed by the reaction of isocyanates and polyols. Fully cured polyurethane products are inert and non-toxic.
The properties of polyurethane are influenced by the types of isocyanates and polyols used to make them. They can range from tough or rigid materials, through to flexible materials.
Polyurethane can be used to make products that are both strong and lightweight, as well as being durable and highly versatile. It is a key ingredient in several types of high-efficiency insulation materials (such as rigid foam insulation panels), For more information, see Polyurethane spray foam in structurally insulated panels and composite structures.
It is also used for paints and other coatings, microcellular foam seals and gaskets, wheels and tyres, sealants, binders and adhesives.
