Abstract: A refrigerator includes an inner liner, an outer wrapper and a trim breaker that extends between the inner liner and the outer wrapper to define an insulated structural cabinet. The trim breaker includes a plurality of gas-blocking flakes, wherein each gas-blocking flake includes a longitudinal axis that extends substantially parallel with an elongated surface of the respective gas-blocking flake. The longitudinal axis and the elongated surface of each corresponding gas-blocking flake is oriented to be substantially parallel with a portion of an outer surface of the trim breaker located near the respective gas-blocking flake.

Abstract: A vacuum insulated refrigerator includes a cabinet defining at least one compartment. The cabinet includes a wrapper, a liner assembly, and a trim breaker assembly coupled to the wrapper and the liner assembly. The trim breaker assembly defines a wrapper groove to receive an edge of the wrapper and at least one liner groove to receive at least one edge of the liner assembly. A wrapper light-diffusing optical fiber is disposed in the wrapper groove. The wrapper light-diffusing optical fiber is configured to diffuse light within the wrapper groove. At least one liner light-diffusing optical fiber is disposed in the at least one liner groove. The at least one liner light-diffusing optical fiber is configured to diffuse light within the at least one liner groove. A light reactive adhesive is disposed in the wrapper groove and in the at least one liner groove.

Abstract: The disclosure provides for a method for preparing a vacuum insulated panel. The method comprises forming an internal cavity between a liner and a wrapper and preparing filler material to be disposed in the internal cavity. The filler material comprises a first part and a second part. Preparing the filler material comprises treating a surface of the first part, wherein the treating prepares the surface to receive a coating comprising a first charge. The preparing further comprises coating the surface of the first part with a chemical comprising a first charge. The coating forms a first surface charge on the surface of the first part. The method further comprises mixing the first part with the second part forming the filler material. The second part comprises a material having a second surface charge opposite the first surface charge.

Abstract: A system for forming insulation packages includes a vessel configured to hold a slurry that includes a liquid and an insulation material. A supply conduit is coupled at a first end with the vessel and has a second end configured to couple with an envelope for selectively supplying the slurry from the vessel to an interior cavity of the envelope. A chamber is configured to selectively maintain a pressure within the chamber at a reduced pressure less than ambient pressure. The second end of the supply conduit is disposed within the chamber. A mold includes an inner mold liner that at least partially defines a cavity for retaining the envelope therein and an outer mold shell that at least partially surrounds the inner mold liner. The inner mold liner and the outer mold shell are gas-permeable and permeable to the liquid.
