Used primarily in the production of polyurethane foams, which are found in a wide range of applications including flexible foams for furniture, mattresses, and automotive seating, as well as rigid foams for insulation in appliances and construction. Also utilized in coatings, adhesives, sealants, and elastomers due to its durability, flexibility, and resistance to wear and abrasion. In industrial settings, it serves as a key component in manufacturing synthetic rubbers and resilient materials for wheels, rollers, and bushings. Additionally, it finds use in some medical devices and biocompatible materials because of its favorable mechanical properties and low toxicity when polymerized.
