发明名称 Sound insulating membranes.
摘要 <p>A sound insulating membrane and processes for forming, particularly well suited for use in floor, ceiling and wall constructions. The membrane comprises at least one backing layer (10,30) in contact with a layer (20) of polymeric material. The polymeric material has an elongation factor of about 500% to about 900% and a Shore A hardness of from about 65 to about 80 points, 5 seconds. In a preferred embodiment, the polymeric material comprises 40-70% chlorinated polyethylene, 20-30% ethylene vinyl acetate, and up to 10% polyvinyl chloride. The membrane may be used between a floor structure (60) and ceramic tiles (70). <IMAGE></p>
