Antistatic masterbatch is formulated in order to eliminate the electric charges on the surface of the polymer. Electric charges tend to cause many problems like attract dust which ruins the clarity of film and surface finishing, damaging electronic equipment. Antistatic additives are used with all polymers in injection molded, extruded applications and blow molded. It functions in molecular or multi -molecular layer and attracts water molecules from the atmosphere. The water lowers the surface resistivity 109 to 1012 ohms. Without antistatic additives, the surface resistivity of plastic is between 1014 to 1015 ohms.
Antistatic masterbatches are used in manufacturing of appliances that are used in washing machines, refrigerators. These are also used for electronic appliances. In order to achieve a higher conductivity, conductive fillers like carbon black, carbon fiber and powdered metal is added to the plastic.
