SGM Prime Air Ultima is a premium lightweight vibration dampener from the SGM Prime line, made from a reduced-mass butyl rubber mastic and 100 µm aluminum foil. An innovative hollow microsphere technology reduces the material’s weight by up to 30% without compromising its damping performance. The material maintains stable characteristics across a temperature range from –40°C to +120°C and offers enhanced adhesion to metal surfaces. The mounting side is protected by silicone-coated paper for easy installation.

At the beginning of 2026, an updated version of the material, the adhesive composition has been improved: increased adhesion ensures instant bonding and reliable fixation without preheating. The adhesive upgrade has made it “smart”: the “smart” adhesion of SGM Prime materials allows for adjustments during installation, with adhesion increasing by 25% within 15–20 minutes and by 60–80% or more after 24 hours.

The material features a matte satin aluminum foil treated with Prime Satin technology. This technology creates a developed micro-rough surface structure, providing a mechanical bonding effect with the mastic. This significantly enhances interlayer adhesion strength and completely eliminates the risk of dust or moisture penetrating between the second layer of sound absorber and the foil of the primary damping layer.

The material now features a new design and new packaging.

With a thickness of 2.1 mm, this vibration dampener is one of the lightest in the entire product range. Its reduced weight makes it an ideal solution for vibration and sound insulation in doors, where reducing the load on hinges is critical, as well as for all weight-sensitive areas such as roofs, trunk lids, and hoods. The enhanced adhesion of SGM Air ensures reliable bonding after roller application without the need for additional heating.
