Abstract

L'invention concerne un flotteur (5) pour un indicateur de niveau, comprenant une matière plastique (7) à base de carburant, un agent porogène (8) et/ou une charge (9). L'agent porogène (8) se présente sous forme de microsphères, qui sont des billes de matière plastique (1) chargées en gaz et la charge se présente sous forme de micro billes creuses (9). Les microsphères (8) et les microbilles creuses (9) sont entourées par la matière plastique (7) à base de carburant.
