Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polyurethane foam for flame lamination which is produced by a process comprising: providing a foam raw material comprising a polyol, a polyisocyanate, a foaming agent, a foam control agent, an amine-based catalyst and a urea compound; and applying a slab method to the foam raw material to provide the polyurethane foam for flame lamination, wherein an average hydroxyl value of the polyol is in a range from 30 to 80 mg KOH/g, and wherein said ure…
