STPBROMO Stp bromo special line: 7mm vibration-damping and sound-proofing material


StP Bromo has combined materials sandwiched together that functions for sound absorption and sound insulation. The open-cell structure of the soft layer effectively dissipates sound and reduces its amplitude. The heavy soundproof membrane reflects penetrating sound waves and prevents them from entering the interior of the car. The front soft covering with a contrasting print makes it easy to distinguish Bromo from other materials and makes cutting the material safer for the craftsman. Combining several functions in one material speeds up the processing process.

Bromo is used in sound insulation for treatment with a second layer, on top of a layer of sheet vibration damper. The material is suitable for application to the floor in the cabin and trunk, as well as to the rear wheel arches on the interior side.
