Abstract

On utilise pour former des éléments de fermeture moulés par injection pour piles galvaniques, une matière thermoplastique à charge minérale, inerte vis-à-vis des électrolytes, par exemple du polypropylène, du polyéthylène et leurs copolymères, la charge minérale étant formée par du talc, du carbonate de calcium, du mica ou une autre matière inerte vis-à-vis des électrolytes, la résistance à l'éclatement ou à la rupture d'une membrane de matière thermoplastique comportant une charge étant inférieure et pouvant etre plus facilement prédite et controlée.
