Polyethylene (PE)

Polyethylene (PE) is primarily used in the packaging industry in the manufacturing of plastic milk and water jugs, detergent and shampoo bottles, and some plastic bags. As a wire and cable insulator and jacketing material, polyethylene is mixed with additives to make it softer and more flexible.

The most common form of PE is solid (non-foamed). Medium-density polyethylene (MDPE), a foamed version of PE, is also available and offers a lower dielectric constant than its solid counterpart. Solid PE carries a low flexibility value, which can vary depending on the density used. Use of High-density polyethylene (HDPE) will further reduce flexibility while Low-density polyethylene (LDPE) tends to increase flexibility. In addition, Polyethylene can be cross-linked to increase its resistance to cracking, cut-through, soldering, and solvents.

Performance of Polyethylene (PE) for Wire and Cable Insulation and Jacketing

Polyethylene is suitable for both wire insulation and final cable jacketing.
