Polyethylene(PE) is one of the most common thermoplastic that used in cable production. First produced by a German chemist Hans Von Pechman in 1898.  PE commercially comes in diffeent density levels. Very low density Polyethylene(VLDPE), Low Density Polyethylene(LDPE),Linear Low Density (LLDPE), Medium Density Polyethylene(MDPE), High Density Polyethylene (HDPE), above table includes data for three most common density levels that are used in cable production. PE also used as base of different halogen free blends. PE is also cross linked. Cross linked Polyethylene( XLPE ) is the most used plastic for medium and high voltage cables.
Applications : PE is widely used in many different cable types. Its' mechanical and electrical properties make it ideal insulation material for Coaxial cables, indoor and outdoor telephone wires ,local area network cables and CCTV cables. Because of its' durability and resistance to sunlight is higher in compare to PVC , PE jacketing replaces PVC in many outdoor applications
