A light weight, vibration-damping composition having effective amounts of at least one butyl rubber, at least one tackifying resin, at least one pigment and substantially spherical microspheres is disclosed. The present composition has a specific gravity of about 1.0 to 1.2 and has effective damping effects at low temperatures as well as temperatures up to about 60 °C. This composition is effective for use in the transportation industry, the building industry, the aerospace industry and the appliance industry. |
