Сar sound absorber SGM Black Block is a specialized acoustic filler made from a fine-cell polyurethane foam with enhanced viscoelastic properties. It is engineered to effectively fill hidden cavities in a vehicle’s body where conventional sound-deadening materials cannot reach. Thanks to its memory effect and controlled expansion, the material conforms perfectly to the complex geometry of enclosed spaces, creating a tight, seamless acoustic seal.

When installed in trunk side cavities, body pillars, and other enclosed openings, the foam expands to form a continuous sound-absorbing layer. Its fine-cell structure — made from a specially formulated polyurethane — effectively dampens sound waves across a wide frequency range, preventing noise from entering the cabin.
