LOW-FUME SELF-EXTINGUISHING CABLE AND FLAME RETARDANT COMPOSITION CONTAINING NATURAL MAGNESIUM HYDROXIDE Russian patent published in 2010 - IPC C23C26/00 H01B7/295 C08K3/22 

FIELD: metallurgy.

SUBSTANCE: self-extinguishing cable contains conductor and flame-retardant coating containing polymer matrix and particles of natural magnesium hydroxide of medium diametre of particles d₅₀, equal to 0.5-5.0 mcm, and average diametre of pores less or equal to 0.35 mcm. Average diametre of particles d₅₀ is determined on assumption, that 50 vol. % particles of natural magnesium hydroxide have diametre bigger, than the said value, while 50 vol. % particles of natural magnesium hydroxide have diametre less, than the said value.

EFFECT: production of cables possessing low-fume, self-extinguishing properties and improved mechanical characteristics.
