Radiation-crosslinked polyethylene for wire and cable applications

Abstract Polyethylene is used as an insulation material for wires and cables because of its excellent electrical properties. Polyethylene is also a typical irradiated crosslinked polymer. The characteristics of irradiated polyethylene, the effects of density, molecular weight and so on, were studied.

Development of halogen-free, heat-resistant, low-voltage wire for automotive use

Abstract Development of the electron beam irradiated halogen-free, heat-resistant, low-voltage wire for automotive use and its properties are discussed in this short report.

Irradiated wires for internal wiring

Abstract Irradiated modified polyolefin and polyvinyl chloride have excellent heat-resistant, mechanical, and electrical properties. In the present paper, wires with modified insulation that are used for the internal wiring of appliances and automobiles are described.

IRRADIATED CROSS-LINKED WIRE

Abstract Generally speaking, polyurethane has excellent mechanical properties but poor water resistance. It is rather difficult to obtain flame retardant polyurethane while maintaining water resistance. We ascertained that improvement in water resistance could be achieved on polyurethane by high energy electron beam irradiation. The irradiated cross-linked polyurethane is very useful as jacketing material for automobile cables.
