Overview
DOW ENDURANCE™ HFDB-0586 BK S is a specially formulated semiconductive, vulcanizable compound designed for use as an extruded conductor shield and bonded insulation shield applications in power cables, especially developed for use in high voltage cables.(1) DOW ENDURANCE™ HFDB-0586 BK S meets stringent requirements for product smoothness. DOW ENDURANCE ™ HFDB-0586 BK S has stable volume resistivity characteristics at elevated temperatures and is formulated with a polymer system that has demonstrated compatibility with copper and aluminum conductors. DOW ENDURANCE™ HFDB-0586 BK S offers outstanding extrusion properties with low melt pressures and low temperature generation that result in outstanding scorch resistance and outstanding smoothness under a wide processing window.

(1) DOW ENDURANCE™ HFDB-0586 BK S is recommended for use in conjunction with DOW cross-linked polyethylene and tree-retardant cross-linked polyethylene compound. For other polymer insulations, the user is cautioned to establish the utility of DOW ENDURANCE™ HFDB-0586 BK S.

Applications
DOW ENDURANCE™ HFDB-0586 BK S has been designed for semiconductive applications in power distribution and transmission cables for cable rated up to 230 kV. It can be used as inner and outer semiconductive layer for bonded cable applications and as inner semiconductive layer for strippable cable constructions.
