Autotools Bitumen mat 500x700x4mm

Vibrofiltr bitumen mat is a self-adhesive vibration-damping material based on butyl rubber, with an aluminium foil layer. It forms an insulating, vibration-damping layer in a car, or anywhere else you need sound insulation and protection against vibration and corrosion.

The mat is flexible, so it goes onto flat surfaces as well as complex shapes, and you fit it without heating. It is waterproof, seals and protects against corrosion. The material has a multilayer structure: a layer of butyl rubber compound and aluminium foil. Vibrofiltr uses high-viscosity aluminium foil.
