ELECTROCONDUCTIVE PEROXIDE CROSS-LINKABLE COMPOSITION Russian patent published in 2013 - IPC H01B3/44 

FIELD: electricity.

SUBSTANCE: electroconductive peroxide cross-linkable composition comprises, wt %: polyolefin 49-62, benzopropionic acid 3,5-bis(1,1-dimethylethyl)-4-hydroxy-2-[3-[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]-1-oxopropyl] hydrazide -0.05-0.20, tetra-bis-methylene-(3-(3,5-di-tret-butyl-4-hydroxyphenyl) propionate)-0.05-0.20, organic peroxide-0.2-1.9, electroconductive technical carbon with specific volume resistance p=10±6 Ohm*cm - 29-34, technical carbon with specific volume resistance p=5±3 Ohm*cm - 2.5-5, 4,4'-thiabis(6-tret-butyl-m-cresol) - 0.05-0.25, zinc stearate - 0.15-1.0, polyethylene wax - 3-9. The composition of the specified compound is not exposed to substantial thermal-oxidative ageing and premature cross-linking during superimposition, and items from it have smooth surface.

EFFECT: improved physical and mechanical properties of cable products made with application of the proposed composition, and its manufacturability and stability.
