ABSTRACT:
A medical-surgical dressing comprising a reinforced sheet of silicone elastomer foam having a thickness not exceeding 10 millimeters, one of the surfaces of the sheet having a surface layer of open cell foam and the other surface having a substantially non-cellular surface skin. The dressing may be manufactured by a process comprising depositing a liquid foamable silicone composition on an absorbent surface, allowing the composition to foam and set to an elastomer and thereafter separating the foam sheet from the substrate.
The dressings are useful e.g. for the treatment of wounds, burns and as liners for plaster casts.
