Abstract
A polymer composition formed by: I) fluoropolymers selected from one or more of the following: copolymers based on ethylene, TFE and/or CTFE modified with hydrogenated monomers, or blends of these fluoropolymers with PCTFE; said fluoropolymers and/or the corresponding blends optionally mixed with hydrogenated plasticizers; II) one or more inorganic fire-retardants, treated and not with dispersing agents; III) one or more crosslinking agents; IV) optional additives.

A polymer composition formed by:
- I) fluoropolymers selected from one or more of the following:
- copolymer based on ethylene, TEE and/or OTFE, modified with hydrogenated monomers having one double bond, or blends of these fluoropolymers with homopolymers of CTFE or (co)polymers based on CTFE (POTFE) containing at least 99% by moles of CTFE, the complement to 100 being one or more fluorinated monomers or hydrogenated monomers;
- said fluoropolymers and/or the corresponding blends optionally mixed with hydrogenated plasticizers;
- II) one or more inorganic fire-retardants, optionally treated with dispersing agents;
- III) one or more crosslinking agents;
- and
- IV) optional additives selected from fillers, intumescent agents, pigments, lubricants, organic fire-retardants and thermal stabilizers;
- the total sum of the percentages of components I), II), III) and optional IV) being 100% by weight.
