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
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
