Insulation & Jacketing Material

      One of the least acknowledged, yet one of the most important aspects of wire and cable manufacturing is the material used for insulation and jacketing. Polyvinyl chloride (PVC) is both purchased in the Philippines and imported from the United States. Only reputable sources are considered for the best grade PVC. Low density polyethylene (LDPE) for jacketing telephone cables and insulating aluminum conductor and high-density polyethylene (HDPE) for telephone wire singles are imported from the European Community and the United States. For higher temperature ratings and for fluid resistance in power cables, cross-linked polyethylene (XLPE) is used. Another material, nylon, is used as an outer jacket over PVC on building wires for the manufacture of THHN.
