Product Description
DGDB-3485 NT is an expandable, high-molecular weight, high-density polyethylene insulation compound specifically formulated for foam/skin telephone singles. It incorporates a chemical blowing agent which enables this material to attain up to 50 percent expansion via temperature-controlled extrusion. This highly stabilized product has superior mechanical and electrical properties and has been designed for high-speed extrusion.

Specifications:
Telephone wire insulated with DGDB-3485 NT using sound commercial extrusion practices, should meet the following cable specifications:
  • REA PE "Filled Telephone Cable with Expanded Insulation"
  • ICEA S-84-608 "Telecommunications Cable; Filled, Polyolefin Insulated, Copper Conductor - Technical Requirements"
