Abstract

A spacer for insulating glazing units is described. The sealing arrangement includes a polymer base; which includes two pane contact surfaces, a glazing interior space surface and an outer surface and an extruded profiled seal on the outer surface, the extruded profiled seal and the polymer base being co-extruded.

First claim

1 .- 15 . (canceled)

16 . A spacer for insulating glazing units, comprising:
a polymeric main body comprising two pane contact surfaces, a glazing interior surface, and an outer surface, and an extruded profiled seal on the outer surface,
wherein the extruded profiled seal and the polymeric main body are coextruded.

17 . The spacer according to claim 16 , wherein the extruded profiled seal contains a component selected from the group consisting of butyl rubber, polyisobutylene, polyethylene vinyl alcohol, ethylene vinyl acetate, polyolefin rubber, polypropylene, polyethylene, copolymers, and/or mixtures thereof.

18 . The spacer according to claim 16 , wherein the extruded profiled seal protrudes laterally beyond at least one of the pane contact surfaces of the polymeric main body.

19 . The spacer according to claim 16 , wherein the thickness of the extruded profiled seal is 0.5 mm to 5 mm.

20 . The spacer according to claim 16 , wherein the polymeric main body contains components selected from the group consisting of polyethylene (PE), polycarbonates (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethyl methacrylates, polyacrylates, polyamides, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), preferably acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylester (ASA), acrylonitrile butadiene styrene/polycarbonate (ABS/PC), styrene acrylonitrile (SAN), PET/PC, PBT/PC, and/or copolymers or mixtures thereof.

21 . The spacer according to claim 16 , wherein the polymeric main body includes at least one hollow chamber.

22 . The spacer according to claim 21 , wherein the glazing interior surface has one or more openings connecting the hollow chamber to a glazing interior.

23 . The spacer according to claim 16 , wherein the polymeric main body contains a desiccant.

24 . An insulating glazing unit comprising
a first pane, a second pane, the spacer of claim 16 , the spacer being a circumferential spacer surrounding the first pane and the second pane, a glazing interior adjacent the glazing interior surface of the spacer, and an external interpane space adjacent the outer surface of the spacer,
wherein:
the first pane contacts a first pane contact surface of the spacer, and
the second pane contacts a second pane contact surface of the spacer.

25 . The insulating glazing unit according to claim 24 , further comprising
a sealant between the first pane contact surface and the first pane and/or the second pane contact surface and the second pane.

26 . The insulating glazing unit according to claim 24 , further comprising an outer seal inserted in the external interpane space.

27 . The insulating glazing unit according to claim 26 , wherein the outer seal contains a component selected from the group consisting of polysulfides, silicones, silicone rubber, polyurethanes, polyacrylates, copolymers, and/or mixtures thereof.

28 . The insulating glazing unit according to claim 24 , wherein the first pane and the second pane contain glass and/or polymers.

29 . A method for producing the insulating glazing unit according to claim 24 , comprising:
coextruding a spacer consisting of a polymeric main body and an extruded profiled seal, fixing the spacer by way of a sealant via a pane contact surface between a first pane and a second pane, performing a pressing operation, and introducing an outer seal into the external interpane space.

30 . A plurality of glazing units comprising the spacer according to claim 16 .
