FOAMING CONDUCTIVITY VANISHING MATERIAL, FUSE AND THERMAL SENSITIVE CURRENT INTERRUPTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a foaming conductivity vanishing material capable of lowering conductivity by heated. SOLUTION: This foaming conductivity vanishing material is a conductive material containing at least a resin, a conductive substance, and a heat-forming type forming agent, and its feature is that conductivity is lowered by heat- foaming. The heat-foaming type forming agent may be a thermally expansive micro-sphere. It is preferable that the foaming conductivity vanishing material has a filmy configuration. The foaming conductivity vanishing material can be used as a fuse.
