Polyurethane foam for flame-laminating
Abstract:
The object of the present invention is to provide a polyurethane foam for flame lamination which has an excellent balance between adhesiveness to a fabric comprising synthetic fibers or natural fibers, a leather or the like and residual compression strain and has an excellent wet-heat resistance, and a laminated body including a foamed material layer consisting of the polyurethane foam. The polyurethane foam for flame lamination is characterized by being produced using a foam raw material containing a polyol such as a polyether polyol, a polyisocyanate, a foaming agent, a foam control agent, an amine-based catalyst and a urea compound such as urea and azodicarbonamide.
