SGM Alpha 4 anti-vibration material
Anti-vibration material from the second highest model series from SGM, which consists of self-adhesive polymer butyl rubber of the new generation and aluminum foil with a thickness of 100 microns. The film with a square embossment and black lacquer is equipped with a modern print, on the assembly side the material is protected by a siliconized film. The anti-vibration material from the Alpha series stands out especially for its top properties, very high acoustic loss factor (MLF), high adhesion to metal surfaces and above-standard stability. An acoustic loss factor of 0.45 units together with a thickness of 4 mm enables a high ability to prevent vibrations. The biggest difference compared to the Beta series is significantly higher efficiency thanks to the special composition of the material, as well as better adhesion to metal and stronger aluminum foil. Like all SGM anti-vibration materials, Alpha series materials are resistant to water, moisture, oils and have anti-corrosion properties..jpg)

Where to apply SGM Alpha 4 anti-vibration material
You can apply SGM Alpha 4 anti-vibration material almost anywhere where you need to reduce vibrations and resonances. However, due to the thickness of 4 mm and the high acoustic loss factor, the material is particularly suitable for areas with a very high vibration load. A suitable area of use is especially the floor, engine partition and front and rear wheel arches. A thickness of 4 mm is unnecessarily thick for other surfaces of the vehicle. The most common uses of SGM Alpha 4 anti-vibration material:- Floor
- The bottom of the trunk
- Front metal wheel arches
- Rear metal wheel arches
- Engine bulkhead
- Central tunnel
- Torpedo
About SGM damping materials
The Russian company SGM Technology was founded in 2006, and since then it has been one of the leading Russian manufacturers of sound and heat insulation materials for the automotive, shipbuilding, aviation and construction industries. The combination of excellent physical properties of materials and technological methods is the result of the highly efficient performance of the specialized workforce of SGM, which consists of specialists from the best technical universities of Russia. Currently, SGM offers over 200 types of materials that meet the strictest quality and stability standards with certification according to ISO 9001: 2008 and ISO / TS 16949. Long-term cooperation with such giants as Bosch or LG is proof of the highest quality of SGM products, which has long been one of the best on the market today. At the turn of 2019 and 2020, the SGM company presented hi-tech noise-reducing materials from the top Prime series, which in their performance slightly surpass even the premium materials of the market leader in noise reduction from Comfortmat. You can buy the products of both highly competitive manufacturers, who are constantly competing with innovations in the field of vehicle sound deadening, on our e-shop with a guarantee of the most technologically advanced and most effective products of today. Thanks to the official representation of our company for the Czech Republic and Slovakia, you can count on sufficient stock and professional service..jpg)

| Acoustic Loss Factor (MLF)The acoustic loss factor (in English, mechanical loss factor) expresses the ability of the material to absorb propagating sound and change the energy of vibrations created by the sound into thermal energy. The theoretical maximum loss factor is 1, which means no vibration. For example, non-sound-proof steel with a thickness of 1 mm has a loss factor of approx. 0.001 at 200 Hz. Therefore, the higher the loss factor, the better. By combining damping materials, it is possible to significantly increase the loss factor to values approaching 1. | 0.45 |
