Sound insulation material SGM Isol BB-Tone 4
SGM Isol BBTone is a multi-layer material that combines three functions - anti-vibration, sound insulation and heat insulation. Isol BB-Tone is made of elastic material in the form of re-foamed polyurethane foam with polymer impregnation in combination with polymer butyl rubber self-adhesive sealant. The first layer of material consists of a 2 mm thick sealant, which dampens vibrations and prevents the development of corrosion processes due to preventing the penetration of moisture. The second layer consists of polyethylene foam with a thickness of 4 mm with a high ability to absorb noise and thermal insulation properties. On the assembly side, the material is protected by siliconized paper. The greatest advantage of the material is its high ability to absorb air-borne noise inside the car and its resistance to significant changes in temperature and humidity. The structure of polyurethane foam with secondary foaming is characterized by the presence of open pores and relatively large cavities between the flakes, so that there is almost no sound reflection. Sound waves are absorbed by the cellular structure of the material. The specially selected structure of the cross-linking composition and polymer impregnation of the material is a unique development of SGM and provides the maximum possible sound absorption characteristics. In addition, Isol BB-Tone is an extremely light material with a weight of only 0.4 Kg / 1 m², which can also be used for installations where the main task is not to increase the weight of the car too much and at the same time effectively dampen it. The material is highly flexible and can be applied even to highly embossed surfaces. The extremely adhesive self-adhesive layer guarantees effectiveness at -40 °C to +120 °C. The material complies with fire safety standards in the automotive industry, the burning rate is less than 100 mm per minute. Available in 4 and 8 mm thickness.

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.| Catalog number | SGM ISOL BB-TONE 4 |

| 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. | 0.12 |
