General rubber is insulated, if need electric conductivity then need to add conductive material, graphite powder has superior conductivity and lubrication demoulding. Graphite is processed into graphite powder, with excellent lubrication, conductive properties, the higher the purity of graphite powder, the better the conductivity. Many special rubber products factory need conductive rubber, then with graphite powder added to the rubber inside can conductive? The answer is yes, but there is also a question, what is the proportion of graphite powder in rubber? Some enterprises use the proportion is not more than 30%, this kind of wear-resistant rubber products above, such as car tires and so on, there are special rubber factory ratio is 100%, such will be conductive, conductive basic responsibility is the conductive body can not be interrupted, like a wire, if the middle of the broken then will not power, conductive rubber inside the conductive graphite powder is the conductor, if the graphite powder is insulated rubber partition, then also do not conductive, so the proportion of graphite powder less conductive effect is not good.
Graphite powder is a very sensitive material of chemical reaction, in different circumstances, his resistivity will change, that is, his resistance value will change, but one thing is not changed, graphite powder is a good non-metallic conductive material, as long as in the insulating object inside to ensure that the graphite powder uninterrupted, like a thin line will also electrify, but, the value of the resistance is not a quasi but the number, because the thickness of graphite powder is not the same, used in different materials and ambient graphite powder resistance value will not be the same.
