ELECTRIC INSULATING SELF-EXTINGUISHING COMPOSITION Russian patent published in 2009 - IPC H01B3/44 

FIELD: electric engineering.

SUBSTANCE: invention is related to the field of electric engineering, in particular to electric insulating self-extinguishing composition, which may be used to manufacture insulation of cables and wires of various purpose. Composition comprises the following components, in wt %, organic halogen-containing compound 5.3÷14.3, antimony trioxide 2.2÷5.7, calcium stearate 0.1÷0.4, vinyl trimetolsilane or vinyl trietoxysilane 1.0÷3.0, organic peroxide 0.1÷0.4, tetra-bis-methylene- (3.5-di-tret-butyl-4-hydroxyphenyl)propionate 0.05÷0.3, benzo propionic acid 3.5-bis (1.1-dimethylethyl)-4-hydroxy-2-[3-[3.5-bis(1.1-dimethyl)-4-hydroxyphenyl]-1-oxopropyl] hydrazide 0.1÷0.5, homo- or copolymers of olefins - the rest.

EFFECT: high resistance of composition to thermal oxidising ageing in process of contact with copper, and also high physical-mechanical characteristics of insulating material from it in manufacturing of cable products from it.
