A spacer for insulated glazings includes a polymeric main body including two pane contact surfaces, a glazing interior surface, an outer surface, and a cavity, wherein the polymeric main body contains a thermoplastic polymer as a base material at a proportion of 30 wt.-% to 70 wt.-%, as an elastomeric additive, a thermoplastic elastomer, and/or a thermoplastic terpolymer having an elastomeric component at a proportion of 0.5 wt.-% to 20 wt.-% in total, and a reinforcing agent at a proportion of 20 wt.-% to 45 wt.-%, the thermoplastic polymer as a base material includes a styrene-based polymer, and the polymeric main body has a foamed pore structure.

Spacer for insulated glazing

A spacer for insulating glazing units is presented. The spacer has a polymeric main body with features that include two parallel side walls that are connected to one another by an inner wall and an outer wall. The side walls, the inner wall, and the outer wall surround a hollow chamber. According to one aspect, the polymeric main body has a glass fiber content of 0 wt.-% to 40 wt.-%, to which 0.5 wt.-% to 1.5 wt.-% of a foaming agent is added to form hollow spaces that provide a weight reduction of the polymeric main body of 10 wt.-% to 20 wt.-%.

Glass-fiber-reinforced spacer for insulating glazing unit

An insulating glass unit suitable for a refrigeration unit is presented. The insulating glass unit includes a first pane, a second pane spaced at a distance from the first pane, a peripheral spacer frame between the first pane and the second pane, and an inner interpane space. According to one aspect, the spacer frame includes four hollow-profile polymeric spacers, which are secured between the first pane and the second pane along one of the four sides of the insulating glass. According to another aspect, the two first hollow-profile polymeric spacers are arranged along two opposing first sides of the insulating glass unit and the two second hollow-profile polymeric spacers are arranged along two opposing second sides of the insulating glass unit. According to yet another aspect, the first polymeric hollow-profile spacers contain 5% to 50% and the second polymeric hollow-profile spacers contain 0% to 0.5% reinforcement fibers.
