Overview
DOW ENDURANCE™ HFDB-0586 BK is a specially formulated semiconductive, vulcanizable compound designed for use as an extruded conductor shield and bonded insulation shield applications in power cables.(1) DOW ENDURANCE ™ HFDB-0586 BK 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 offers outstanding extrusion properties with low melt pressures and low temperature generation that result in outstanding scorch resistance under a wide processing window.

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

Applications
DOW ENDURANCE™ HFDB-0586 BK has been designed for semiconductive applications in power distribution and transmission cables for cables rated up to 150 kV. It can be used as inner and outer semiconductive layer for bonded cable applications and as inner semiconductive layer for strippable cable constructions.
