Abstract

A dimensionally heat recoverable article carrying a thermoplastic polymeric material and a heat-softenable adhesive of smaller thickness and lower softening or melting point than the polymeric material is used to encapsulate objects such as joints in cables. The heat-softenable adhesive allows low installation temperature while the polymeric material allows excellent cycling performance to be maintained. The article may be in the form of a wrap-around sleeve.
