ABSTRACT:
An orthopedic cast material is disclosed, which, when wrapped about a body member and cured by exposure to visible light, forms a rigid, high strength immobilizing structure and which comprises an air, light and X-ray permeable fabric impregnated with a formulation comprising (a) acrylate terminated polyurethane oligomers or ethylenically unsaturated polyesters or polyethers, (b) functional acrylate monomers as optional diluents and (c) a photoinitiator which is activated by visible light to initiate the polymerization reaction, whereby the casts produced therefrom show no tendency towards discoloration in ambient light or sunlight, are aesthetic in appearance, are dry to the touch and possess good whiteness.
