A flame-retardant polymer composition comprising a mineral filler and a polymer, said mineral filler comprising a calcium compound, characterized in that the calcium compound is a fire-resistant additive in the form of calcium hydroxide, having a specific surface calculated according to the BET method greater than 25 m/g, preferably greater than 30 m2/g, more preferably greater than 35 m2/g and advantageously greater than 40 m2/g, uses of same and the combustion residue obtained.

Flame-retardant and fire-resistant polymer compositions made from lime having a high specific surface

A mineral filler in a flame-retardant organic polymer composition comprising a calcium compound for a fire-resistant effect characterized 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.
