antiphon® MPM^TM - vibration damping sandwich material

Effective material to dampen structure borne sound

antiphon® MPM^TM is the most effective structure borne sound damping material related to weight and serves a dual function. It dampens the structure borne sound and it replaces the structural sheet metal that would otherwise be used, usually without any increase in the thickness and weight of the materials. The structure borne sound damping material can often eliminate the need for special screening or sound absorption, which would otherwise take up a considerable amount of space and increase the weight of a product.

Formable and weldable metal sandwich

antiphon® MPM^TM is a formable and weldable sandwich consisting of two metal facing sheets enclosing a visco elastic inner layer. The two metal facing sheets in antiphon® MPM^TM are in most applications of cold rolled steel, but in principle any type of metal or alloy can be used. Today the material is produced with laminated cold rolled steel, metallic coated steel, stainless steel and aluminium.

Acoustic visco elastic inner layer

The inner layer is optimised for different temperature ranges between -5 C and +125 C. In this way it is possible to achieve maximum vibration damping of structure borne sound when the sandwich material is used in various applications such as engine parts, vehicle bodies, white goods or office machines.
