Title:
MULTILAYER BARRIER MATERIALS WITH PVD OR PLASMA COATING FOR VACUUM INSULATED STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2017/116578
Kind Code:
A8
Abstract:
A method of forming a vacuum insulated structure includes providing a multi-layer sheet of material comprising at least one layer of barrier material that is disposed between first and second outer layers. The barrier material and the first and second outer layers comprise thermoplastic polymers. The multi-layer sheet of material is thermoformed to form a non-planar first component. The first component is at least partially coated utilizing a plasma polymerization process or a physical vapor deposition process to improve the barrier properties of the first component. The method further includes securing a second component to the first component to form an interior space therebetween. Porous filler material is positioned in the interior space, and a vacuum is formed in the interior space.
