The Wes mir is one of the leading suppliers of sound insulation materials and
the manufacturer of Keeptek® acoustic insulation

KeepTek®

KeepTekKeepTek® acoustic insulation is a high-quality modern material based on the production technology of nonwoven thermally bonded materials of polyester microfibres for professional noise insulation.

It is used in the automobile industry to reduce engine, transmission and suspension noise levels on various road surfaces, and in various weather conditions. It is supplied both in the form of a web (isolation of hidden cavities, luggage compartment, etc.) and as mouldings (insulation of the cover sheet of the engine compartment on the driver's side, internal insulation of the hood).

It is used by leading manufacturers of the Russian automobile industry.

The material is used mainly in the automobile industry but is also required in house building and industrial engineering, aircraft, ship, and car building to ensure sound insulation and greater comfort. KeepTek® means improved technical characteristics, durability and economic efficiency.

KeepTek® Micro

KeepTek® Micro

KeepTek® Micro

Description:

The material has high sound-absorbing properties and is used in many places of a car, for example, in door panels, instrument panels, rack lining, trunk shelves, etc. The material easily shrinks, does not collapse during installation and operation, has a small weight and is easily cut. Available with black protective polypropylene film on one side.The film surface is embossed.

Esignatory properties:

The material is suitable for passenger and luggage compartments, especially for insulating vertical surfaces. The part can be made in the traditional way, such as cutting and thermal splicing. The fastening ofthe material on parts and components is recommended using the method of ultrasonic welding or a point heat-sealing, but also an adhesive method of attaching (adhesivetransfertapes or hot-melt glue) can be used.

The material is made from hydrophobic fibers (the ability to absorb moisture less than 1%), which virtually eliminates the risk of mold and odors. The product can be used in humid conditions.

Basic properties:

The composition ofthe base layer: 100% polyester.
Colour: white.
For ease ofinstallation, the material is adhesive on one side.

Physical parameters:

thickness - 14 mm
surface density - 255 g/m2
biostability (no mold and odor)
non-flammable, burning rate is not more than 100 mm/min
no residual burning
temperature range from -50°C to +120°C
moisture absorption is not more than 0.2%

Application:

Used as acoustic and heat insulating cladding in roofs, doors, racks, wheel arches of cars.
