Abstract: A method for producing a heat-shrinkable product is provided. First, a polymer composition containing a polymer, a crosslinking agent and a micro-encapsulated foaming agent uniformly dispensed therein is melt mixed. The foaming agent has a peak activation temperature which is higher than a temperature of the melt mixing. Next, the polymer composition is injection molded into a molded product. This carried out at the peak activation temperature to activate the foaming agent. Then, the molded product is crosslinked within the mold.

Abstract: A cross-linkable composition includes an elastomeric fluoropolymer and a semi-crystalline fluoroplastic. The composition enables manufacturing of articles which maintain favorable mechanical properties (e.g. tensile strength, elongation and flexibility) when continuously exposed to extreme temperatures. In addition, a cross-linked product obtained by subjecting said composition to ionizing radiation is disclosed, which may be used in heat-shrinkable articles, cable jackets and sealing elements.

Abstract: An article and process are described. The article includes a conductive heat-recoverable composite shield or a conductive heat-recovered composite shield formed from a conductive heat-recoverable composite shield. The conductive composite shield and/or the conductive heat-recovered composite shield formed from a conductive heat-recoverable composite shield comprises a non-conductive matrix and conductive particles within the non-conductive matrix. The article has a resistivity of less than 0.05 ohm·cm. A process of producing the conductive heat-recovered composite shield includes extruding the conductive heat-recoverable composite shield and heating the conductive heat-recoverable composite shield thereby forming the conductive heat-recovered composite shield.
