Material Notes:
ApplicationsPETROTHENE HR 92953 is a medium density polyethylene-based resin designed for use as jacketing for communications cable, including CATV and FOC. HR 92953 has a nominal carbon black content of 2.6% and antioxidant has been added to ensure thermal stability during processing.Processing TechniquesHR 92953, like other thermoplastic polyolefin compounds, can be extruded as wire and cable insulation using a conventional extruder. Below are suggested extrusion conditions for HR 92953. These conditions are intended as general guidelines only and are not optimum values, since manufacturing conditions, such as extruder type and size, affect the processing of thermoplastic compounds.This product is from the former Equistar product line.
