Applications
PETROTHENE LR 5900-05 is a high density, high molecular weight resin designed for primary insulation for electronic cables. This resin exhibits low shrinkback after extrusion, contains a lower level of antioxidant than the standard LR 5900-00, and is not suitable for the telecommunications applications for which LR 5900-00 was formulated. Antioxidant has been added to LR 5900-05 along with a metal deactivator to ensure thermal stability during processing and to prevent degradation from copper while the cable is in service, respectively.
Processing Techniques
LR 5900-05, like other thermoplastic polyolefin compounds, can be extruded as wire and cable insulation using a conventional extruder. Below are suggested extrusion conditions for LR 5900-05. 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 the processing of thermoplastic resins.
Industry Specifications
LR 5900-05 meets the requirements of the following: ASTM D1248-2, Type III, Class A, Category 4, Grades E8 and E9; Federal LP 390C, Type 11, Class H, Category 4, Grade 1; REA PE-22; REA 7CFR 1755.390.This product is from the former Equistar product line. |
