A great sound insulation materials of mass loaed vinly sound barrier，it is a flecible ,noe-reinforced mass loaed vinly materials ,application for floor ,ceilign or wall .reduce sound wave and reduce transmission of airborne noise .the biggest feactures that mass loaed vinly sound barrier is a strong resistance to adverse environmental conditions ,oils ,weak acides and alkalis .
those mass loaed vinly sound barrier can be composited with acoustic foam ,sound panel ,Soundproof nonwovens，Aluminum foil，etc it like a protection layer ,can help us to reduce noise .
