Abstract
A method of forming a heat-recoverable article including the steps of profile extruding polymeric material into a predetermined shape, irradiating the polymeric material and then deforming the polymeric material into a generally planar configuration. Also disclosed is a heat-recoverable article including a generally planar layer of polymeric material which is in the heat unstable condition. Opposed surfaces of the polymeric material have a latent recovery stress, however opposite in sense, so that the article upon recovering towards a predetermined shape, exhibits substantially no residual stress. Further disclosed is a heat-recoverable article made by the method.
