ELECTRICALLY INSULATING COMPOSITION Russian patent published in 2010 - IPC H01B3/44 

FIELD: chemistry.

SUBSTANCE: composition contains the following in pts. wt: copolymer of ethylene and vinyl acetate 60-85, high-density polyethylene which is modified with maleic anhydride 15-35, magnesium or aluminium hydroxide 130-170, polyethylene wax 0.1-5, ester of 3,5-di-tert-butyl-4-hydroxyphenyl propionic acid and pentaerythritol or 1,3,5-trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene 0.05-0.7, benzopropionic acid 3,5-bis(1,1-dimethylethyl)-4-hydroxy-2-[3-[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]-1-oxopropyl]hydrazide 0.05-0.3, nanoclay 10-20.

EFFECT: increased strength, elongation at failure and hardness of cable sheath, low flammability of the electrically insulating composition and low toxicity due to exclusion of halogen-containing compounds in the composition.
