urethanes
Flexible foam materials
Urethanes are chemical compounds formed by reacting an alcohol with an isocyanate, widely used in making foams, coatings, adhesives, and elastomers.
The term often refers broadly to polyurethane materials: urethane foam insulation, urethane floor finishes.
In industrial contexts, urethanes offer durability and flexibility, appearing in everything from car bumpers to skateboard wheels.
