Spacer for insulating glazing

A spacer for insulating glazings comprising a polymeric main body at least comprising a first pane contact surface, a second pane contact surface, a glazing interior surface, an outer surface, and a hollow chamber,

• wherein
• the first pane contact surface and the second pane contact surface run opposite one another and parallel to one another,
• the glazing interior surface and the outer surface are connected to one another via the first pane contact surface and the second pane contact surface,
• the hollow chamber is enclosed by the glazing interior surface, the outer surface, the first pane contact surface, and the second pane contact surface,
• the outer surface has a first angled section adjacent the first pane contact surface and a second angled section adjacent the second pane contact surface,
• the first angled section and the second angled section assume in each case an angle α of 120° to 150° relative to the respective adjacent first pane contact surface and second pane contact surface, and the polymeric main body has at least one corner inside the hollow chamber within a cross-section perpendicular to a longitudinal direction of the polymeric main body and in a region of at least one of the first and second angled sections and the respective first or second pane contact surface adjacent thereto, which corner is rounded with a radius R1 of 0.4 mm to 2.5 mm,
• the polymeric main body has, within said cross-section in the region of the first angled section and the region of the second angled section, at least one corner inside the hollow chamber with the outer surface, which corner is rounded with a radius R2 of 0.4 mm to 2.5 mm,
• the glazing interior surface assumes in each case an angle β of 87° to 93° with the first pane contact surface and the second pane contact surface, and the polymeric main body has, within said cross-section, a corner inside the hollow chamber in a region of the glazing interior surface and the first pane contact surface and/or the second pane contact surface, which corner is rounded with a radius R3 of 1.0 mm to 2.5 mm.
