Abstract
A self-adhesive vibration damping tape for adhering to a substrate is provided. The tape is formed from a vibration damping composition comprising a synthetic rubber polymer, a thermoplastic polymer, a plasticizer, and an organic filler comprised of recycled automotive paint powder. The composition is preferably formed into a tape which includes a release liner on one surface and an aluminum foil facing on the other surface. In use, the tape is adhered on one surface to a substrate such as an automotive or appliance part to provide vibration damping properties as well as seal out the infiltration of air, dust and moisture.
Claims18
A self-adhesive vibration damping tape comprising:
- a vibration damping composition comprising a synthetic rubber polymer, a thermoplastic polymer selected from the group consisting of amorphous polyolefins ethylene-based copolymers, and ethylene based terpolymers;
- a plasticizer, and an organic filler comprising recycled automotive paint powder;
- wherein said vibration damping composition is in the form of a tape having first and second major surfaces.
In combination, a self-adhesive vibration damping tape and a substrate comprising:
- a vibration damping composition provided in the form of a tape having first and second major surfaces, said tape being laminated on said first surface to an aluminum foil facing;
- said vibration damping composition comprising a synthetic rubber polymer, a thermoplastic polymer selected from the group consisting of amorphous polyolefins, ethylene-based copolymers, and ethylene-based terpolymers, where said amorphous polyolefins are selected from the group consisting of polypropylene-ethylene copolymers, polypropylene/polypropylene-ethylene copolymers, polypropylene homopolymers, polyethylene homopolymers, and mixtures thereof;
- a plasticizer, and an organic filler;
- wherein said vibration damping tape is adhered to said substrate on said second surface.
A self-adhesive vibration damping tape composition comprising:
- from about 5 to 10% by weight of a synthetic rubber polymer;
- from about 1 to 10% by weight of a thermoplastic polymer selected from the group consisting of amorphous polyolefins ethylene-based copolymers, and ethylene based terpolymers;
- from about 15 to 30% by weight of a plasticizer;
- and
- from about 5 to 50% by weight of an organic filler comprising recycled automotive paint powder.
A self-adhesive vibration damping tape comprising:
- a vibration damping composition comprising a synthetic rubber polymer, a thermoplastic polymer comprising an amorphous polyolefin selected from the group consisting of polypropylene-ethylene copolymers, polypropylene/polypropylene-ethylene copolymers, polypropylene homopolymers, polyethylene homopolymers, and mixtures thereof;
- a plasticizer, and an organic filler;
- wherein said vibration damping composition is in the form of a tape having first and second major surfaces including an aluminum foil facing laminated to at least one major surface of said tape.
