、固定剤は白い状態そのままであった。An aluminum etched foil measuring 37×1 g00 mm was chemically converted in a boric acid solution at 300 V. This anode foil and aluminum cathode foil were wound to form an element. The rating is 200V,
It was 5-80uF and the size was 30φ×50C. This element was impregnated with a predetermined electrolytic solution for driving an aluminum electrolytic capacitor. This element was sealed in an aluminum case using fluororubber as a fixing agent. This element was directly heated to around 200°C, and the combustion state was observed by bringing a flame close to it. Since it is thermosetting, it did not melt even at around 200°C. When the fire was brought close, smoke appeared in about 15 seconds, and flames were seen in about 25 seconds, but the flames quickly went out. When the element was disassembled, it was found to be black and burnt, but the fixative remained white.

Smoke appeared in 0 seconds, and flames could be seen in about 20 seconds. The flame was not as strong as pitch, but it was stronger than fluoro rubber. When the element was disassembled after self-extinguishing, there was evidence that atactic polypropylene had flowed into the element, and further evidence that the electrolyte and atactic polypropylene had been burned together in the element was also confirmed.
