New Insulation Material Yields Smaller, Lighter, Greener Cables
More InfoLess Info
A new alternative wire insulation to PVC offers better performance and significantly less environmental impact. Although PVC insulation is a mainstay of the wire and cable industry due to its mechanical and electrical properties and its low cost, it presents environmental issues due to its halogen content. Halogens are elements such as fluorine, chlorine, bromine and iodine that are highly reactive and can be harmful to people and animals. PVC contains approximately 29% chlorine by weight; in fact, the C in PVC is chloride, an ion of chlorine. Teflon FEP and PTFE contains up to 76% fluorine and, when burned, produces toxic acid.
