MULTILAYER MATERIAL USABLE PARTICULARLY AS DAMPING MATERIAL

摘要

A multilayer material is described, comprising a first layer having a modulus of elasticity between 70 and 150 N/mm 2 coupled to a second layer comprising a reticulated viscoelastic material comprising at least one acrylic resin. The modulus of elasticity of said material is preferably between 1*10 7 N/m 2 and 1.80*10 9 N/m 2 and the acrylic resin is present in the viscoelastic material in percentage by weight between 25 and 50%. The multilayer material of the present invention is preferably used as damping material.
