Insulating materials of new generation

To improve the performance of the noise level in the vehicle interior and outside is quite real due to the additional funds the repayment of acoustic and mechanical vibrations. Another thing is that this can be achieved only in a limited range limit. However, those few decibels reduction in the intensity and pressure of sound is quite enough for a comfortable and pleasant feelings inside or in the immediate vicinity of people.

The modern market of insulating materials

From the wide range of implemented products is not always possible to find the best option. In retail outlets often come across poor quality materials, they can be exposed to temperature factors, lose their original properties, and in many cases have to deal with outright fakes who are unable to have any significant effect on the acoustics of the car.

In this regard, it is very important to know a proven brand and trusted vendors of the noise and its attendant tools. Here primarily are due to vibration-absorbing, teploizoljacionnye, cushioning and decorative materials. In this article, we present the products one of the leading Western manufacturers, proven with the best hand and provides reliable protection from unwanted and harmful factors. It has a wide range of applications, including various types of cars, buses, tractors, other farm equipment and vehicles.

Soundproof materials

Among the wide range of items, the isolation of sound vibrations to select multiple species, widely represented in the domestic market of car accessories. They are implemented as separately in the form of standard sheets for subsequent cutting and in ready sets for General and local applications.

• Ruby-ML – range of products that eliminates the noise propagation for prodelyvanija its occurrence. The basis of their structure lies polyvinyl chloride Mylar tape coated with fine metal particles and a polyurethane layer (10-20 mm.) On its surface is applied an adhesive protected by a detachable film. An extra option is low conductivity, which allows to maintain the necessary thermal regime. The sound absorption coefficient of the material ranges from 0.4 to 0,94 units. While it retains the acoustic efficiency in the frequency range 600 - 4000 Hz. It is also characterized by the reliability of fastening on a supporting surface with increased strength more than 4 N/cm These protective tools are most suited for installation on the hood and trunk.
• Ruby-15ML – one of the best representatives of the family of products sound insulation. Its front part is zvukopodrazhanii Mylar with a metallic coating based on a polyurethane foam with a thickness of 15 mm. For easy mounting to the surface to be protected on its surface the self-adhesive composition. Prevention of ignition or burnout of its surface and the deterioration of the noise-reducing properties is provided by an oil-resistant coating. All the indicators are efficiency, reliability, and efficiency are within the values characteristic of the material is Ruby.
• Poly-8 – noise tool more simple in comparison with the Ruby family structure, but perfectly performs the function of noise absorption. In addition, consistently high and remain teplosernaya properties. It consists of a polyethylene foam and has a polystyrene structure, it is characterized by resistance to moisture and other environmental factors that have the way to complicated and specific climatic conditions. The number in the name indicates the layer thickness - 8 mm. This material is mainly used for application on the interior floor or the bottom of the trunk.
• Poly-8L – one of the performances of the above material on the basis of polyethylene foam. It has the same characteristics and properties, provides excellent insulation space from the noise and heat gain or heat loss. Its feature is the flexibility and convenience of drawing on the surface located vertically and the items of complex configuration. Therefore, the scope of its application are the wheel arches, tunnels, front wall of hall, etc.

Describes protective measures to retain their properties and functions in a temperature range from minus 40 to plus 100 ?C.

Means of vibration absorption

Protective devices that prevent or reduce the frequency and amplitude of oscillations of mechanical systems, are designed to soften and neutralize secondary sources of occurrence of extraneous noise when the engine is running and the vehicle is moving.

• Bany-M1 has a high degree of flexibility and elasticity, which is an inherent property of any vibration protection. It consists of special polymer composition with a layer of aluminum foil across the work surface. It has a high resistance to temperature, atmospheric and corrosive factors, largely providing a sealing function. Seamlessly installs on complex curved and hard-to-reach parts of the machine, it does not require the holding of dermopathology. The thickness of the material corresponds to the designation in the name of the M1 is 1.5 mm. the Reliability of its fixing on the carrier surface reflects the strength indicator that has a value of about 5 N/cm Mechanical losses characterizes the ratio of 0.13 units.
• Vib-PB2 – vibration protection tool, made of polymer-bitumen mixture with a layer of adhesive for mounting on housing parts. The numeric value of the name indicates its thickness is 2 mm. It is also resilient to moisture, sunlight, heat, or fuels and lubricants. The measure of mechanical losses is 0.12 standard units. The installation of this material requires special pre-heating of the heat gun or Hairdryer to a temperature of + 40?C. the Best way to use it with the device vibration protection cabin floor and the bottom of the trunk.

Seal connections and joints

Important role in combating the sources of noise playing seals, which provide maximum contact and a stable position adjacent parts. For these purposes we can recommend the following tools.

• Bit – sealing material of polyurethane foam, which also provides good sound insulation and space. Comes in two thicknesses 5 and 10 mm. the quality is determined by the presence and thoroughness of impregnation, which increases water resistance, elasticity, abrasion resistance and gives the ability to withstand natural ultraviolet. It is mounted on the roof, the adjacent parts of the interior, wheel arches and other contiguous parts of the body.
• Bit-5L – tool seal with a set of properties of products of this series. A polyurethane layer is the thickness of sheet 5 mm. In greatest extent eliminates the characteristic creaking plastic trim panel and details of the internal structure of the vehicle.
