method for thermal production of composites from foams unvernetzter thermoplastics such as polyaethylen, polyvinyl chloride, polystyrene and the like, and other flaechigen formations with polyurethane foam as haftvermittler, respectively. as interlayer

摘要

Composite materials, from polyethylene or PVC foams, and opt. with other materials such as textiles, films, initation leather and laminates, which have a polyurethane foam as an inter. layer, are made by heating successively the upper and lower faces of the polyurethane foam, and sticking these surfaces to the faces of other materials by pressure.
