High Performance Conductive Blacks for Plastics
Polymer Materials are inherently electrically insulating materials, meaning they do not conduct electricity. To make plastic materials conductive, a special type of carbon black is utilized. Once a certain concentration of Carbon Black Pigments is exceeded, the resistivity drops drastically by several units to the power of 10 (Percolation). After Percolation, the resistance continues to decline slower with increasing Carbon Black Pigment concentration. Orion Engineered Carbons offers one of the best solutions on the market for electrical conductivity.
Orion’s PRINTEX Kappa 70 & PRINTEX Kappa 20 are recommended for modifying the antistatic and electrical conductivity characteristics of polymers. The required level of Carbon Black Pigments is depending on the type of Conductive Black used in the polymer system, the processing method and the requirements which must be met. Conductive polymer materials are used for packaging of sensitive electronic components, such as cable compounds for conductor shielding and jacketing, in floor coverings, carpet backings, conveyor belts, air conduits and in injection hoses for explosives. Applications for these carbon blacks include wire & cable, electronic packaging, ATEX (atmospheric explosion), ESD (Electro-static Discharge), and EMI (Electro Magnetic Interference)/RFI (Radio Frequency Interference) Protection applications. PRINTEX Kappa 70 & PRINTEX Kappa 20 helps to strike a balance between electrical conductivity, process ability, and performance. Some of the benefits include:
• Outstanding dispersibility, mechanical stability, and viscosity properties
• Highly conductive Carbon Black at low concentrations
• No negative impact on rheological properties
