Patent DE-3835638-A1 (DE)
Title: Elastic, thermoplastic insulating material, in particular as a packaging material and for thermal and solidborne sound insulation, and a process for the preparation thereof, and a starting material suitable therefor
Inventor: MOSER HEINRICH
IPC: C08J9/232
Filed: 1988-10-19
Abstract: The insulating material can be formed, for example, from rigid polystyrene foam. It is also possible to use PE foam. However, the materials are either expensive or have, for example, the inadequate long-term durability and dynamic strength values for solidborne sound insulation. In order to improve this, a corresponding insulating material is produced from expandable polystyrene which is first superexpanded and immediately thereafter shrunk again by from 10% to 50%. During subsequent interim storage, a post-expansion is carried out with absorption of oxygen. These process steps can be repeated a number of times. The insulating material is particularly suitable for solidborne sound insulation and for the packaging sector.
