ABSTRACT:
New damping (insulating) materials are based on polyvinyl chloride particles or balled up fibers which are extremely lightweight and have a bulk density of 10-200 g/l and a particle weight less than 1 g. The particles are either enveloped by sheets or combined into lightweight components by means of heat or by the addition of binders, such as adhesives, fusion (hot-melt) adhesives, curable polymers, or frothed (pre-foamed), expandable polymers.
