Noise-absorbing material SGM BB-Tone 4
SGM BB-Tone is a noise-absorbing material made from an elastic material in the form of re-foamed polyurethane foam with a mounting adhesive layer. The material’s greatest advantage is its high ability to absorb airborne noise inside the vehicle and resistance to significant changes in temperature and humidity. BB-Tone is an extremely lightweight material weighing only 0.4 kg / m², developed especially for installations where the main task is not to add too much weight to the vehicle while still providing effective soundproofing. The material is highly flexible and can be applied to very contoured surfaces. The extremely adhesive self-adhesive layer ensures effectiveness from -40 °C to +120 °C. The material meets automotive fire safety standards; the burn rate is less than 100 mm per minute. Available in thicknesses of 4 and 8 mm. Please note that the final color of the material may differ from the photograph, depending on the current source of raw materials used in production.
