SOUND SORBER WITH METALLISED FILM
Soundsorber foam is an acoustic grade polyurethane foam with a metallised polyester facing. Sorber/MYL is designed
to obtain maximum sound absorption per given thickness through the uniform cell structure of the polyurethane foam. |
|
The metallised facing offers protection against petrol, grease, oils etc, and also enhances the acoustic characteristics
in the low frequency range.
Application:
Sorber is a 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.
 
|
Benefits
- Excellent acoustic absorption properties
- No irritating fibres or dust particles
- The standard pressure sensitive adhesive (PSA) used has good chemical and weather resistance while giving effective
adhesion over a long period when applied to clean dry surfaces
- Vibration resistant
- Impermeable to dust, grease, oil, petrol and any other fluids
- High tear resistant surface
- Ignition retardant (test report available)
- Easy to cut, bend and install
- Resistant to UV, ozone & chemical attack
- Australian made
|
Options:
- Hydrolysis resistant polyether polyurethane foam is recommended for areas in contact with exhaust fumes, moisture
or humidity
- All sorber foams can be supplied with a pressure sensitive adhesive (PSA) backing
- The standard PSA used exhibits initial tack and adhesion to clean dry surfaces and provides high shear &
heat resistance
- A polyurethane sealer is available for exposed edges
- Other surface or colour finishes
- Soundguard offers facilities for die cutting and CNC fabricating to customer requirements
- Soundguard products are available from 3mm to 100mm thick
- Soundsorber foams can be combined with barrier and dampening layers to improved their acoustic performance.
