Medical bandage material which is extendible in several directions and which is liquid-tight, comprises a layer of polyurethane and a fabric layer which is extendible in all directions, the fabric layer being embedded in the thickness of the polyurethane layer and the fibres in the fabric layer being at least 6 cm long. Pref. the fabric layer is roughly in the centre of the polyurethane layer, the material has a wt. of 20-130 g/m2 andis between 15 and 120 microns thick, and consists of a polyurethane layer with a wt. of 15-80 g/m2 in which a fabric layer of 5-50 g/m2 is embedded. The fabric is esp. of polyolefin, polyester or polyamide fibres or glass fibres. The material pref. has an elongation at rutpure of more than 60% in all directions. The bandage is pref. in the form of an adhesive plaster type dressing with an adhesive applied to the polyurethane layer and a layer of fabric covering at least part of the adhesive layer on the side opposite the polyurethane layer. The free side of the adhesive layer may be covered by at least one anti-adhesion coated protective foil. |
