Sound deadening plates

The sound deadening plates can mainly be used for the vibration reduction of metal sheets, as well as the increase of the noise isolation level. The main field of application is the vehicle and machine industry, e.g. air conditioning techniques, ventilator manufacturing. Furthermore they can also be used in the households for the noise reduction and insulation of high performance equipment e.g. wall vacuum cleaners, extractor fans, pipes built in the wall, and the tubes of these built-in pipes.

These sound deadening plates can be used for chassis, doors and machine compartments of vehicles. The flexible elastomer bitumen base material has excellent crack bridging properties, and is particularly good for noise reduction of fine metal sheets.

Properties:

  • Self-adhesive surface
  • High flexibility even at low temperature
  • Suitable for the improvement of bending stability of thin-walled construction materials
  • Provided with protective foil
  • Wide temperature tolerance range

Field of application:

These sound deadening plates are suitable for noise insulation of machines, commercial vehicles, private cars, air transport equipment, air conditioning equipment and elevators.

STP SILVER

These elastic sound deadening plates are self-adhesive, flexible and easy-to-mould even at low temperature. They reduce the vibration, the noise and have heat-insulating properties as well, providing a ’luxury car’ feeling.

STP SILVER is a self-adhesive, flexible and elastic, 2mm-thick sound insulating material. This sound deadening sheet is a multilayer combination of an aluminum foil and a polymeric layer on butyl rubber base (alu-butyl). The material is water resistant and highly resistant to environmental impacts; furthermore having corrosion-preventing and sealing properties. The recommended range of temperature tolerance is from 45°C below zero to 130°C above zero. A short-term exposure at the temperature of 190°C is also allowed. The polymeric layer on the base of butyl rubber allows an easy mounting of the material to various-shaped surfaces, and unnecessitates the preheating of the material before use. It is suitable for the application on dry corrosion-preventive materials, too.

Field of application:

These sound deadening plates can be used for the noise reduction of cars, trucks, transportation vehicles, machine industry and air conditioning techniques.
