Dow™ Wire & Cable DFDK-6050 NT is an enhanced linear low density polyethylene resin which can be used as a cable jacketing material when properly colored and stabilized. The material exhibits a combination of properties like improved toughness, strength and high heat resistance, while demonstrating good flexibility, excellent environmental stress crack resistance and excellent processing properties. With its well balanced mechanical and processing characteristics DFDK-6050 NT is an excellent jacket grade for power cables and telecommunication cables.

Processing Recommendations:
DFDK-6050 NT can be extruded using a range of conventional commercial jacketing extruders. Typical extruder barrel temperatures required depend on many factors such as extruder size.
A good starting point is: 140/190/200/200/200/200°C with melt temperatures below 250°C.

Applications:
DFDK-6050 NT is a natural resin that needs to be blended with carbon black or colored pigment masterbatches with a suitable UV - stabilizer to ensure sufficient weathering resistance. The addition of a proper antioxidant level is required for long term ageing resistance. A carbon black masterbatch with extra antioxidant for use with DFDK-6050 NT is Dow™ Wire & Cable DFDK-6010 BK.
