Soundsorber foam is an acoustic grade polyether polyurethane foam
with a reinforced aluminium foil facing. Sorber / AL is designed
to obtain maximum absorption per given thickness through the uniform
cell structure of the polyurethane foam. The reinforced aluminium
facing offers protection against petrol, grease, oils and offers
flammable surface and also enhances the acoustic characteristics
in the low frequency range.

Sorber A/L is highly effective sound absorber with a tough, wear
resistant and impermeable surface for applications such as generators,
enclosers, compressors, engine compartments, bus truck and under
bonnets insulation, hydraulic pump enclosures and marine engine
compartments and duct linings.

Soundsorber
foam is an acoustic grade polyurethane foam with a thin polyurethane
film facing. Sorber / PU is designed to obtainmaximum sound absorption
per given thickness through the uniform cell structure of the polyurethane
foam. The thin polyurethane facing offers protection against petrol,
grease, oils etc., and also enhances the acoustic characteristics
in the low frequency range.

Sorber / PU is highly effective sound absorber with a tough
flexible and impermeable surface for applications such as generators,
enclosures, compressors, engine compartments, bus truck and car
under bonnets insulation, hydraulic pump enclosures, marine engine
compartments and duct linings.

Soundsorber
foam is an acoustic grade polyurethan foam with a perforated vinyl
facing. Sorber /PR is designed to obtain maximum sound absorption
per given thickness through the uniform cell structure of the polyurethane
foam. The perforated facing offers a durable and attractive decorative
surface, and also enhances the acoustic characteristics in the low
frequency range.

Sorber / PR is a highly effective sound absorber with a tough
flexible and attractive surface for applictions such as a bus, truck
or car head liners and side panels, analytical covers and office
equipment enclosures.
