An insulation material that is based on polyvinyl chloride and can be used for cables or wires is disclosed. Additives for flame retardation as well as stabilizers and processing aids are added to the base material. The composition comprises 100 parts polyvinyl chloride, 40 to 60 parts polymer plasticizer (softener), 10 to 50 parts magnesium carbonate, 10 to 50 parts of a metal hydrate, and 5 to 15 parts of a zinc-tin compound. In case of fire, the insulation material emits low amounts of smoke.
