Abstract
Vibration damping material in which polyvinyl chloride (PVC) and a particle filler such as fly ash or talc are amalgamated into a matrix by combination with a small percentage by weight of blown asphalt in a heat working process, such as extrusion, for forming a product such as a sheet of the material. By use of blown asphalt as a compatibilizer and amalgamator, waste or recycled PVC such as of electrical wire strippings combined with a filler has provided excellent damping characteristics.
