Tecnocell SA

Tecnocell SA is a sound absorbing material of foamed polyurethane with open cells. The product is based on Acusticell SA but its surface is embossed and treated for extra ordinary acoustically properties.
The material can be bent and is self-adhesive. Can be combined with a mat for structure-borne sound damping and airborne sound insulation.

Areas Of Application

Factory machinery, fans, mills, printing and timber handling equipment, electric generating sets, generators, engines.

Transportation and vehicles
Scooters, Contractor’s and Gardening Machinery.

Hospital care and large-scale kitchens
Vacuum Cleaners.

Computers, printers, picking and enveloping machines, copying machines.

Method of use
The parts are cut or stamped to the required shape and carefully pressed on to a surface that must be free from oil, dirt, and dust.


  • Extra ordinary sound absorption
  • Aesthetically attractive surface
  • Workable, also for 3-D applications
  • Fireresistant

The shaping and positioning of the material is of major importance to achieve an optimal sound-dampening effect. Sontech has long experience of practical noise control projects in a wide range of industrial fields. These experiences can be a valuable addition to the laboratory data given in the datasheet. Sontech can also assist with advice and sound measurements for noise control and in the manufacture of customised material sets.
