is produced from bitumen with added mineral fillers and synthetic rubber. This highly viscoelastic material is designed to minimise acoustic and vibration radiation of sheet metal. It also improves airborne sound insulation performance , due to its high specific mass. The full self-adhesive backing makes the material easy to install.
Bitumen based damping sheets are used as vibration damper for engines, electrical equipment, metal furniture, metal sheets ….. They are applicable as sound insulation in engine rooms of machines, vehicles, boats, building ans construction.
