ETHYLENE PROPYLENE COPOLYMER PROVIDES A VERSATILE AND STABLE INSULATION,
Abstract
Steady field development by the wire and cable industry has led to commercial use of EPR and submission of building and appliance wires to Underwriters Labs. Established properties indicate that flexible EPR wire can be used in high and low voltage applications as insulation and jacketing. Inertness to ozone and excellent corona resistance combined with other good physical and electrical properties will permit unipass construction in some types of wires and cables. Damage tests at 300C. and heat aging at intermediate temperatures indicate EP insulation should qualify for continuous service at 90 -130C. (Class B) and be used in network cable, motor lead wire, etc. Ability to be flameproofed, fair oil resistance, flexibility at low temperatures and toughness, make EP rubber of special interest for use as a jacket.
