Abstract
Halogen-free electric wires with superior heat resistance of 125°C and 150°C respectively have been developed, based on establishing proprietary technologies of flame retardance and an anti-aging agent system in addition to application of electron beam cross-linking. The halogen-free wires developed here proved to provide excellent mechanical properties and heat resistance, and were confirmed to meet the vertical flame retardance specifications of VW-1. The wires were subjected to chemical substance elution tests and combustion fumes analysis tests, and no toxic substances were detected with the wires.
