Polyurethane Wikipedia.
They are used to increase the load-bearing properties of low-density high-resiliency HR foam as well as add toughness to microcellular foams and cast elastomers. Initiators such as ethylenediamine and triethanolamine are used to make low molecular weight rigid foam polyols that have built-in catalytic activity due to the presence of nitrogen atoms in the backbone. A special class of polyether polyols polytetramethylene ether glycols which are made by polymerizing tetrahydrofuran are used in high performance coating wetting and elastomer applications. Conventional polyester polyols are based on virgin raw materials and are manufactured by the direct polyesterification of high-purity diacids and glycols such as adipic acid and 14-butanediol.

Polyurethane rigid foam systems are used as an insulating foam material in construction entry doors and appliance refrigerators freezers etc. In addition polyurethane rigid foam systems are also used to make faux wood and furniture moldings. Rigid polyurethane is sometimes also used together with composite technology as a core and then covered with composite material such as fiberglass to reduce weight. Applications of this technology range from wind-blades for the wind power industry to a spoiler on a car to learn about release agents for the molding of composite materials read our main Composite Molding applications page.
