Polyurethane --

Polyurethanes are widely used in flexible and rigid foams, durable elastomers and high performance adhesives and sealants, fibers, seals, gaskets, condoms, carpet underlayment, and hard plastic parts. Polyurethane products are often called "urethanes".

Uses - Over three quarters of the consumption of polyurethane products is in the form of foams, with flexible and rigid types being roughly equal in market size. Polyurethane materials are also used in coatings and varnishes used in furniture manufacture, carpentry or woodworking. Polyurethane is also used as an adhesive, especially as a woodworking glue. Its main advantage over more traditional wood glues is its water resistance. It is also used in making solid tires. Modern roller blading and skateboarding became economical only with the introduction of tough, abrasion-resistant polyurethane parts.
