Описание материалов:

DOW ENDURANCE™ HFDA-0581 BK is a specially formulated semiconductive, vulcanizable compound designed for use as an extruded strand conductor shield and bonded insulation shield applications in medium voltage crosslinked polyethylene insulated cables.(1) DOW ENDURANCE™ HFDA-0581 BK has stable volume resistivity characteristics at elevated temperatures and is formulated with a polymer system that has demonstrated compatibility with copper conductor.

Specifications
DOW ENDURANCE™ HFDA-0581 BK is designed for use in power distribution cables. Cables with conductor and insulation shielding of DOW ENDURANCE™ HFDA-0581 BK, prepared using sound commercial fabrication practice, would be expected to meet the following specifications:

ANSI/ICEA: S-94-649, S-97-682, S-93-639 / NEMA WC74

AEIC: CS8

IEC: 60502

(1) DOW ENDURANCE™ HFDA-0581 BK is recommended for use in conjunction with DOW cross-linked polyethylene and tree-retardant cross-linked polyethylene compounds. For other polymer insulations such as EPR and EPDM's the user is cautioned to establish the utility of DOW ENDURANCE™ HFDA-0581 BK with each formulation.

Дополнительная информация
Nominal property values above represent tests on molded, stress-relieved slabs. Cure times were 15 minutes at 175°C.Storage The environment or conditions of storage greatly influences the recommended storage time. Storage should be in accordance with good manufacturing practices. If proper warehousing and storage temperatures [dry conditions, between 50°F and 86°F (10°C and 30°C) in temperature] are utilized, this product may be stored by the customer for up to one year. It is recommended that the practice of using the product on a first-in / first-out basis be established. Storage under extreme conditions may affect the quality, processing, or performance of the product.

Инструкции по экструзии
DOW ENDURANCE™ HFDA-0581 BK provides excellent surface finish and outstanding output rates over a broad range of conditions. For optimum results, melt extrusion temperatures in the suggested range of 240 to 285°F (115 to 140°C) to avoid pre-cure or scorch. Extruder barrel settings of 110°C (230°F) are suggested as a starting point while learning to process DOW ENDURANCE™ HFDA-0581 BK. Specific machine settings will depend on the extruder design and must be established through conventional practices. Dehumidified hopper drying at 140°F (60°C) for up to 6 hours may be employed to remove moisture prior to extrusion.
