Abstract: The present invention relates to a thermoplastic composition suitable for manufacturing a thermoplastic sheet for producing a medical cast, such as a radiation mask. The composition has a polymeric component comprising a mixture of a styrene acrylonitrile copolymer and polycaprolactone, optionally together with a cross-linker and/or a filler, wherein the polymeric component comprises, 20 to 40 weight % of a styrene acrylonitrile copolymer and 80 to 60 weight % of a polycaprolactone, expressed in weight % of the polymeric component, wherein the thermoplastic composition has a glass transition temperature of 35° C.-80° C. The invention further relates to a thermoplastic sheet and to a medical cast, in particular a radiation mask, obtainable from said composition. In a final aspect, the invention relates to a method for producing said sheet and said radiation mask.

Abstract: A flexible thermoplastic sheet material (100) is disclosed, suitable for molding to and immobilising a part of a subject during medical treatment. The flexible thermoplastic sheet material has a core layer (10) with an upper surface (1) and lower surface (2), that is a thermoplastic composition including polycaprolactone and polyurethane. A first outer layer (5) is disposed over the upper surface of the core layer, having a material formed from a yarn which includes polyamide and elastane. The second outer layer (15) is disposed over the lower surface of the core layer and includes open cell foam with layers which are bonded so as to form a single sheet. A cushion and molding frame can be made from the sheet material (100).

Abstract: A pre-fabricated orthosis suitable for embracing and supporting a body part of a human or animal is disclosed. The orthosis has an articulation and may be made from a pre-formed sheet of material containing cork and a thermoplastic binder. The orthosis may be uniformly perforated in its central part and may be composed of a mixture of cork and ethyl vinyl acetate (EVA). A method of manufacturing the orthosis is also disclosed.
