Petrothene LR590005 is a high density resin selected by customers for use as primary insulation for electronic cables. This resin exhibits low shrinkback after extrusion, contains a lower level of antioxidant than LR590001, and is not suitable for the telecommunications applications for which LR590001 was formulated. Antioxidant has been added to LR590005 along with a metal deactivator to ensure thermal stability during processing and to prevent degradation from copper while the cable is in service.

Petrothene LR590005 meets the requirements of the following: ASTM D 1248-2, Type III, Class A, Category 4, Grades E8 and E9; Federal LP390C, Type II, Class H, Category 4, Grade 1; REA PE-22; REA 7CFR 1755.390.
