  • Low density attached polyurethane foams made by containment of blowing agents during foam processing
    Patent number: 9469718
    Abstract: Polyurethane cushions are formed on the surface of a textile such as carpet. The polyurethane is made in the reaction of a polyurethane forming composition that is frothed, and contains water as a blowing agent.
