Abstract: A spacer is provided that is shapable into a spacer frame, and during manufacture of an insulating glass unit, can be mounted on the glass panes. The spacer is formed having an inner surface, an outer surface and two lateral surfaces extending at either side of the spacer from the inner surface to the outer surface, and comprises a profiled body. The profiled body comprises two mutually spaced lateral faces running parallel to its longitudinal direction and a base body that extends between the lateral faces and has an outer and an inner face. The profiled body comprises at least in one part of its volume a quantity of particulate desiccant that is embedded in a plastics material. The spacer is coilable about an axis, perpendicularly to the lateral surfaces, and takes a flexurally rigid form in a plane perpendicular to the lateral surfaces.
