A popular application in the automotive industry sound dampening becomes more and more of interest to manufacturers producing polymer parts that will benefit from having sound damping or deadening properties. For example, silent waste pipes is an area where noise reduction is rising in importance especially in high-rise construction and new buildings.
Sound damping made easy
MagniF is used to give extra density to a polymer and therefore to produce heavy compounds. MagniF is very easy to disperse into a variety of plastics or rubbers, be it polypropylene or polyamide. It is possible to reach densities of above 2g/cm³, which is very difficult to reach with other standard mineral products. High filling levels of 60-80 wt% are typical in sound dampening applications to ensure transmission reduction or elimination.
