Antiphon MPM Metal-Polymer-Metal
Sheets
- An acoustic material laminated metallic sheet material
Antiphon MPM,
the most effective structure-borne damping material related to
weight, serves two functions. It damps structure-borne sound and
replaces the structural sheet metal that would otherwise be
used, usually without any increase in thickness and weight of
the materials. Antiphon MPM can often eliminate the need for
special screening or sound absorption, which usually increases
the volume and the weight of a product.
Antiphon MPM is a
formable and weldable laminate, consisting of two metal sheets
enclosing a viscoelastic inner layer. In most applications, the
two metal sheets are cold rolled steel, but in principle any
kind of metal or alloy can be used. The commonest materials are
cold rolled steel, metallic coated steel, stainless steel and
aluminum. The inner layer is optimised for different temperature
ranges between -5 C and +125 C. It is possible to achieve
maximum damping of structure-borne sound when the material is
used in various products such as engines, vehicle bodies, white
goods or office machines.
