DOW™ Electrical & Telecommunications DGDK-6862 NT
Описание материалов:
Dow AXELERON applied to self-coloring™GP K-6862 NT polyethylene resin is a kind of high density polyethylene resin, which can be used as cable sheath material after proper coloring and stabilization treatment. This material has high hardness, high toughness, high tensile strength, and higher heat resistance. In addition, it also has good flexibility, excellent environmental stress cracking resistance and good processing performance.
Due to its unique performance combination of HDPE and MDPE, Dow AXELERON™GP K-6862 NT is especially suitable as a sheath material for power cables and telecommunication cables.
Processing advice:
Dow AXELERON™GP K-6862 NT extrusion processing can use many common jacketed extruders. Typical extruder barrel temperature depends on many factors, such as extruder specifications and head size. A better starting point is:
when the melting temperature is lower than 250°C, the extruder barrel temperature is set to 140/190/200/200/200/210/210°C.
Application fields:
Dow AXELERON™GP K-6862 NT is a primary color resin that can be blended with carbon black or color masterbatch and a suitable UV stabilizer needs to be added to ensure sufficient weather resistance. It is necessary to add an appropriate amount of antioxidant to ensure its long-term aging resistance.
These sheaths can be used for power cables and telecommunications cables, including fiber optic cables.
Storage:
Storage environment and storage conditions will greatly affect the storage time of materials. Storage under extreme conditions may affect the quality, processing or performance of the product. Storage should be carried out in accordance with good manufacturing practices, for example, the storage environment is dry and the storage temperature is between 10 and 30°C.
