Heat recoverable articles

摘要

The invention relates to a heat recoverable article, such as heat-shrinkable tubing which is used as an insulating sleeve for an electrical cable connection or terminal arrangement. The tubing is formed from a polymer material, and has an inner adhesive layer formed on its inner surface. A resin composite containing ethylene alkyl (meth) acrylate carbon monoxide copolymer is used for the inner layer. A heat shrinkable tubing is obtained which possesses outstanding adhesive properties in relation to an associated adherent material, without suffering from foaming during the manufacturing process since this inner layer exhibits relatively little hygroscopic properties.
