DOW ENDURANCE™ HFDK-4202 EC Polyethylene Compound is a long life water tree retardant, unfilled, crosslinkable low-density polyethylene compound. The permanent tree retardant additive provides improved performance service involving exposure to moisture while retaining the excellent physical, electrical and processing attributes of crosslinkable polyethylene.

DOW ENDURANCE HFDK-4202 EC compound provides electric utilities with:

• State-of-the-art "water" tree-retardant technology, consistently outperforming conventional XLPE in all accelerated cable wet aging tests at ambient and elevated temperatures

• Technology which has been proven in the field for over 25 years, demonstrating excellent reliability and help achieving lowest life cycle costs

• Excellent electrical performance demonstrated by very high aged electrical strength and very low aged dissipation factor and power loss.

DOW ENDURANCE HFDK-4202 EC Compound represents the state-of-the-art in tree-retardant, power cable insulation compounds.
