EB Irradiation of Heat Shrink Tubes & Moulded Components

Apar’s Electron Beam technology is very useful for irradiation of Polyolefin extruded tubes used for Cable jointing kits and to repair the insulation on wires or to bundle them together, to protect wires, and to create cable entry seals, offering environmental sealing protection for connections, joints and terminals, Bus Bar sleeves, Cable end caps etc. Heat shrink tubing is a mechanically expanded extruded polyolefin tube which shrinks when heated in an effort to return to its relaxed original diameter. Heat shrink tubing is rated by its expansion ratio. Heat shrink tubing (thin wall tubing to rigid, heavy-wall tubing) is manufactured by cross-linking either by chemical process or under electron beam. It is a proven fact that such tubes cross linked under electron beam have more uniform cross linking and therefore obtain higher shrink ratio, more uniform shrink properties etc.

The under beam handling system at Apar is suitable to handle almost all varieties of heat shrink tubes and moulded components. Apar does not manufacture these tubes, instead offers its electron beam system on service center basis to various manufacturers engaged in production of heat shrink tubes and components.
