griwephon® Sound Deadening
The Silent Problem Solver for Railway Vehicles and Structural Engineering.
Sheet metal can generate unwanted noise and vibrations due to oscillation and droning, affecting quality and comfort in vehicles, machinery or other applications.
To effectively tackle this annoying problem, the use of griwephon® sound deadening mass offers a highly effective solution.
griwephon® is a specially developed sound deadening mass that is applied to thin-walled sheet metal to dampen vibrations and reduce unwanted droning. This compound adheres firmly to the surface of the sheet metal and forms a protective layer that absorbs vibrations and converts them into heat. This not only significantly reduces the volume of noise, but also improves the durability and structural integrity of the sheet metal.
The application can be of great benefit in various areas such as cars, aeroplanes, ships, industrial machinery, escalators, lifts, railway vehicles, building construction, façade elements and household appliances. Through the targeted reduction of vibrations and the associated noise reduction, griwephon® makes a significant contribution to improving products and creating a more pleasant environment.
griwephon® Series
Products in the griwephon® series are solvent-free sound deadening masses based on aqueous synthetic resin dispersion with sound-absorbing and insulating properties.
They are produced in an environmentally friendly way, from low-pollutant raw materials and without organic solvents.
griwephon® sound deadening masses achieve high sound absorption, adhere optimally to a wide variety of substrates, are flame-retardant and thermally insulating, which is proven by numerous test certificates and approvals. griwephon® series - simple and versatile to use.
Unique. Sustainable.
With an impressive solid content of almost 80 % and continuous further development on an aqueous basis, we are setting standards in the environmentally friendly production and processing of sound deadening masses.
This gives our products a unique selling point and guarantees sustainability in the production and processing of sound deadening masses.
