Abstract
A composite article comprising a fibrillated polytetrafluoroethylene (PTFE) matrix, electrically conductive particles, and energy expandable, electrically nonconductive hollow polymeric particles, which composite is conductive and allows for the flow of electricity and which, upon attaining a temperature which causes expansion of the expandable polymeric particles, becomes insulating and causes the flow of electricity to cease. The articles are thin and can be used as electrical circuit breaking elements.
