The PA6 (nylon 6) of high comprehensive performance is that engineering plastics develop earliest kind, is described as epoch-making engineering plastic
Material.PA has excellent wearability, impact resistance and self lubricity；But nylon 6 is all tool as most of high polymer materials
There is the dielectric of good electrical insulation capability, its sheet resistance is general 1014~1015Ω, electric conductivity is much smaller than metal material,
Easy static electricity gathered lotus after contacting or rubbing with other materials.The negative interaction that accumulation of static electricity is brought be hinder normal production and
Work, or even can set off an explosion and fire.Therefore in the specific work environments of the industries such as underground coal mine, textile equipment, electronic apparatus
Or under dynamic operating condition, it is desirable to anti-static function is also presented while with higher mechanical property in the product of nylon 6, i.e.,
Sheet resistance is down to 1011~1012Ω or volume resistance reach 1011Ω cm, to meet the property requirements used.But because
A large amount of fire retardant, the additions of antistatic additive so that PA6 mechanical property is substantially reduced, and strengthens PA6 because of the " candle wick of fiber
Effect " makes its more easy firing.So this is accomplished by so that nylon ensures the mechanical property of nylon again while anti-electrostatic fire retardant
Can, current material can not meet the requirement.
