DOW ENDURANCE™ HFDK-0587 BK S is a crosslinkable semi-conductive compound based on an ethylene copolymer, and a select clean furnace type carbon black providing excellent smoothness compared to standard semicons.
DOW ENDURANCE HFDK-0587 BK S offers outstanding extrusion properties. Low pressure and temperature generation result in outstanding scorch resistance and excellent smoothness under a wide processing window.

Applications
DOW ENDURANCE HFDK-0587 BK S is recommended as conductor and bonded insulation shielding for high voltage XLPE power cables. DOW ENDURANCE HFDK-0587 S is especially developed for use in high voltage cables, where it provides a clean and smooth interface with the insulation XLPE. DOW ENDURANCE HFDK-0587 BK S provides a good resistance to welding when high degassing temperatures are used.
DOW ENDURANCE HFDK-0587 BK S is preferably combined with DOW ENDURANCE™ HFDK-4201 SC, or DOW ENDURANCE™ HFDK-4300 SC insulation compounds.
For EHV applications, the use of DOW ENDURANCE™ HFDK-0801 EHV is recommended for use as conductor shielding.
