  • Publication number: 20220299255
    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.

  • Publication number: 20220205709
    Abstract: A method and system for forming an insulation package for use in a vacuum insulated structure is provided. A slurry containing a liquid and an insulation material is formed. The slurry can be supplied to an envelope under vacuum, wherein the envelope is gas-permeable and permeable to the liquid. At least a portion of the liquid is drawn through the envelope and at least a portion of the insulation material is retained within the envelope to form an insulation package. One or more insulation packages can be disposed within an insulating cavity and the insulating cavity can be evacuated to decrease a pressure therein to form a vacuum insulated structure.

  • Publication number: 20220099238
    Abstract: A method for preparing a vacuum insulated panel includes forming an internal cavity between a liner and a wrapper and preparing a filler material to be disposed in the internal cavity. The filler material includes a first part and a second part and is prepared by treating a surface of the first part. A coating is applied to the surface of the first part with a chemical having a first charge. The coating forms a first surface charge on the surface of the first part. The method further includes mixing the first part with the second part forming the filler material. The second part includes a material having a second surface charge opposite the first surface charge.
