Abstract

Conductive polymer compositions, particularly PTC compositions, which contain alumina trihydrate, or another arc-controlling agent, and a lubricant or coupling agent. Advantages which can result from use of the lubricant or coupling agent include improved PTC behavior and improved adhesion to metal conductors, in particular metal foils and solid metal wires.
