Abstract
An insert for sealing and acoustic damping of a longitudinal cavity having an interior surface, comprising: a) one or more carrier plates made of a polymeric material (A) which does not deform when heated to a temperature not higher than 180° C. and which comprises a main polymer (A1) which gives mechanical strength to the carrier plate, and—at least one vibration-damping polymer (A2), and b) a thermally expandable material (B). The vibration-damping polymer (A2) is preferably selected from the group comprising: thermoplastic polyurethanes, styrene/butadiene block copolymers, hydrogenated styrene/butadiene block copolymers, styrene/isoprene block copolymers, hydrogenated styrene/isoprene block copolymers, styrene/isoprene/styrene tri-block copolymers, and hydrogenated styrene/isoprene/styrene tri-block copolymers. The invention further includes methods of manufacturing such inserts by injection molding, as well as a method of damping air-or structure-borne vibration in a longitudinal cavity with the aid of such an insert.
