Compressible pillar for a vacuum insulated glazing unit

Abstract

A compressible pillar is disclosed for the preparation of a vacuum insulated glazing (VIG) unit, having a longitudinal extent in a longitudinal direction when in an uncompressed state, and comprising: a deformable part comprising an open structure, wherein the open structure at least partially collapses under a compression force acting in the longitudinal direction of the compressible pillar, the compression force being of at least one value selected within the range of 60 N to 320 N such as a value of the compression force being selected from the range of 60 N to 140 N, from the range of 140 N to 230 N, or from the range of 230 N to 320 N, wherein the longitudinal extent of the compressible pillar decreases to a compressed longitudinal extent when the compressible pillar is subjected to the compression force, and wherein the compressed longitudinal extent of the compressible pillar increases to an expanded longitudinal extent when the compression force is released, wherein the increase in the longitudinal extent is less than the decrease in the longitudinal extent. Furthermore is disclosed a process of manufacturing a compressible pillar, a method of producing a vacuum insulated glazing unit by the use of such pillars and a vacuum insulated glazing unit comprising such pillars.
