The series of fillers are mainly conductive carbon black, graphite and carbon fibers, and the volume resistivity of the finished product is 102-109 Ω·cm. Among them, carbon black filling is the mainstream, and carbon black filled conductive polymers are widely used, one is because the price of conductive carbon black is relatively low; the other is because carbon black can have a larger choice according to different conductivity requirements. The resistance value of its finished product can be varied within a wide range between 102-109 Ω; the third is long-lasting and stable conductivity; therefore, it is an ideal antistatic material. However, its finished products are limited to black, and have a great influence on material properties, and need to be modified.
In foreign countries, carbon-filled conductive plastics have formed into a very mature market. The larger manufacturers include Cabot Corporation, Former Carbon Company, GE Company, 3M Company, etc., Toshiba Chemical of Japan, Sumitomo Phenolic Plastics are the main manufacturers, as well as Toray, Toyo Ink Manufacturing, Tokyo Ink, Japan Synthetic Rubber, Kobe Steel, etc., Finland's PREMIX, South Korea's LG.
