product advantages
- excellent acoustic absorption
- optimal insulation property (thermal insulation)
- good absorption performance
- Incombustible
Acoustic insulation for engine compartments
DBW provides an effective noise control in the engine compartment and interior simultaneously providing for high thermal insulation.
biosil® PT6 is an innovative absorption material for engine compartment encapsulation, which
considerably reduces the noise emission in motor vehicles. Additionally, the increasingly higher
temperatures in the engine compartment are drastically reduced by the low thermal
conductibility.
In close cooperation with our partners in the automotive industry,
biosil® PT6 was developed to meet market needs. It has gained widespread acceptance as an
effective acoustic and thermal barrier.
Thanks to new manufacturing technologies, DBW
Advanced Fiber Technologies offers low basis weights starting from a minimum weight of 500g/m².
This development enables biosil® to be used effectively in a wide range of new applications,
which could not be realized in the past due to a minimum grammage of 1.000g/m². The new product
line of biosil® PT6 advanced is mainly focusing on applications in the area of hood liner and
outer dash insulations for passenger cars and specific applications in light-weight
constructions.
Applications
The molds of DBW fulfill a multitude of
functions in transmission tunnels and automotive bulkheads. They ideally meet the desired requirements
through the exact adaptation in the shape of the cutting, the material combination and the material
strength. The tunnels and bulkheads of DBW are used for engine hood damping
and for external bulkhead and transmission tunnel insulation.
Furthermore, they are applied
in close to engine capsules and as insulation for underbody shields. Its combination with thermal
aluminum shields ensures compliance with very extreme requirements.
Conclusion: These
elements serve for sound absorption and thermal insulation. In addition, they are non-combustible and
thermally stable. They contain a low percentage of binder.
Sandwich elements = more effective systems
The combination of different materials is
a technically sophisticated solution to consolidate individual product properties into an effective
structural part. Sandwich structures combine a high static rigidity for supportive and protective
functions with good heat or sound insulation.
Our material for interior and underbody applications
bicomat® was developed for applications where acoustically effective components with high rigidity are needed. It is a thermoplastic composite material consisting of polypropylene and long chopped glass fibers.
bicomat® suites interior applications, such as trunk compartments, headliners, hat shelves, or even for the underbody
Our product is used by well-known automotive customers as well as manufacturers of agricultural and construction machinery.
As desired by the customer various composites are possible:
