A curable sheet comprising first and second curing reactants arranged in discrete areas of the sheet, preferably by coextrusion, in patterns such as stripes and checks. The sheet cures upon fusion of the respective areas of the curing reactants.

Curable sheet

A process for the production of a marker sleeve assembly which comprises deforming a substantially non-cross-linked web of polymeric material at a temperature below the crystalline melting point or softening point of the material to render the web heat-recoverable, fusing together parts of the web or parts of the web and at least one other polymeric web to define a plurality of radially inwardly heat-recoverable marker sleeves, disposed in side-by-side relationship and preferably separable and subsequently cross-linking the resulting assembly.

Polymeric articles

Marker sleeve assembly

A process for the production of a heat-recoverable wraparound closure having a closure means along at least one of a pair of opposed edge regions thereof which includes the steps of fusing together substantially non-cross-linked parts of a polymeric material which is or may be rendered heat-recoverable, or a substantially non-cross-linked part or parts of said material and at least one other substantially non-cross-linked polymeric material to produce the configuration of said closure means and subsequently cross-linking the substantially non-cross-linked polymeric material.

Heat shrinkable wraparound closures

A process for the production of a hollow heat-recoverable article provided with a functional insert which comprises deforming a substantially non-crosslinked polymeric material at a temperature below the crystalline melting point or softening point of the material to render the material heat-recoverable, disposing said functional insert in contact with an exposed portion of said material, fusing together parts of the deformed material or a part or parts of the material and at least one other polymeric component to produce at least one hollow heat-recoverable article with the functional insert located therein and subsequently cross-linking the substantially non-cross-linked polymeric material.

A wiring harness, and a method for making it, which comprises positioning the wires in a desired configuration and applying a bonding agent as a fluid coating. The method is especially suitable for use with wires insulated with crosslinked polymer insulation.
