LyondellBasell Petrothene® LR590001 High Density Polyethylene

ApplicationsPETROTHENE LR590001 is designed as primary insulation for telephone singles. LR590001 is a high density resin designed for low shrinkback after extrusion. Antioxidant has been added to ensure thermal stability during processing. The resin also contains a metal deactivator to prevent degradation from copper while the cable is in service.Processing TechniquesLR590001, like other thermoplastic polyolefin resins, can be extruded as wire and cable insulation using a conventional extruder. Below are suggested extrusion conditions for LRWC409. These conditions are intended as general guidelines only, and are not optimum values, since manufacturing variables such as extruder type and size have an effect on processing of thermoplastic resins.Industry SpecificationsLR590001 meets the requirements of the following: ASTM D 1248-2, Type III, Class A, Category 4, Grades E8 and E9; Federal LP 390C, Type II, Class H, Category 4, Grade 1, REA PE-22, REA PE-39.
