| abstract |
A process for the manufacture of a dimensionally recoverable article comprises forming a plurality of separate component parts thereof, joining the component parts together to form the article, cross-linking the polymeric material from which the parts are formed after they have been joined together, and then expanding the article. n The process enables dimensionally recoverable articles of complex shape to be manufactured by high speed moulding processes or extrusion processes without the need for curing of the article during formation thereof. |
