Abstract
A mineral filler in a flame-retardant organic polymer composition comprising a calcium compound for a fire-resistant effect characterised in that said calcium compound comprises at least calcium hydroxide, use of same and the combustion residue obtained therefrom, and polymer sheaths for electrical cables containing the mineral filler in the flame-retardant polymer composition.

A mineral filler in a flame retardant organic polymer composition comprising a calcium compound in order to obtain an effect of fire resistance, comprises of a calcium compound that contains at least calcium hydroxide.
The use of a mineral filler containing calcium hydroxide by way of a fire resistance additive in a flame retardant organic polymer composition.
A polymer sheath for electrical cables characterised in that it contains by way of a fire resistance additive a calcium hydroxide as a mineral filler for a flame retardant organic polymer composition.
A combustion residue of a flame retardant polymer composition, characterised in that the residue is a cohesive residue having an average compressive mechanical breaking strength which is greater than 3 kPa, preferably greater than 8 kPa, in a preferential manner greater than 20 kPa, and in a particularly advantageous manner greater than 60 kPa.
