Description
Car sound deadening SGM Alfa 4 mm is a premium automotive vibration damper from the Classic line. It combines a high-adhesion butyl rubber compound with a 90-micron aluminum foil to effectively damp panel vibrations and provide reliable corrosion protection. With an operating temperature range of -40°C to +100°C, it ensures stable performance in various climates. The material features a self-adhesive backing with siliconized release paper for easy and clean installation.
Its maximum 4 mm thickness delivers a high level of vibration absorption in the most heavily loaded areas: the floor, trunk, and wheel arches. Use an application roller to ensure the mastic bonds tightly to the metal.
Important: For optimal performance and durability, avoid direct application to surfaces in immediate proximity to high-temperature components such as the engine, exhaust manifolds, or the exhaust system.
Advantages
- The highest MLF among Classic line vibration dampers;
- Ideal efficiency in the most vibration-loaded areas;
- High-adhesion mastic with corrosion-inhibiting properties;
