Abstract
For the manufacture of breast prostheses from a shell-shaped body made from an addition-vulcanising two-component silicone rubber mass, which body is enclosed in a plastic sheet sheathing said body, a filler of fairly low density composed of hollow spheres or microspheres is added to the two-component silicone rubber mass. The mixture is filled into a sheath of plastic sheet and is cured in a mould under the effect of heat. To obtain the most uniform distribution possible of the filler in the prosthetic body, the mould filled and degassed in the customary way is turned continuously through one or two axes before and during the curing of the two-component silicone rubber mass until the silicone rubber is vulcanised to such an extent that any rising of the filler materials is prevented.
