Applications
PETROTHENE LR686001 is designed for use as insulation for foam/skin telephone singles, and is a natural, expandable, high density polyethylene compound containing a chemical blowing agent. LR686001 is highly stabilized to ensure OIT retention and thermal stability during processing, oven aging, and in pedestal testing. This product contains a processing aid and a metal deactivator to prevent degradation from copper while the cable is in service. Manufacturing advancements have improved dispersion of the chemical blowing agent in LR686001, resulting in superior cellular structure in the expanded insulation. The improved cellular structure may result in decreased spark failures and increased foaming level.Processing Techniques
LR686001, like other thermoplastic polyolefin compounds, can be extruded as wire and cable insulation using a conventional extruder. Below are suggested extrusion conditions for LR686001. These conditions are intended as general guidelines, not optimum values, since manufacturing variables such as extruder type and size have an effect on processing of thermoplastic compounds. Industry Specifications
LR686001 meets the requirements of the following: ASTM D 1248, Type III, Class A, Category 4, Grade E9; Federal LP 390C, Type II, Class H, Category 4, Grade 1; REA PE-89. |
