GEHR-ESD 9® is a variant of POM-C with reduced surface resistance. Unfilled thermoplastic materials made of plastic are electrically insulating and are classified as non-conductors. By means of certain modifiers, such as treated carbon black, metal fibres or certain salts, however, an inherently acting electrical conductivity can also be introduced. This can result in antistatic, static dissipative or even very conductive properties. The aggregates used are not subject to migration, so that continuity of this special property is ensured. In our standard programme we have the following electrically conductive materials in stock: GEHR PE-ELS®, GEHR POM-ELS® and GEHR PVDF-ELS®. Due to market-specific requirements, we have now added an electrically conductive type to the technical materials: GEHR POM-ESD 9® has a static conductivity with a surface resistance of between 106 Ω and 109 Ω. This favours applications in sensitive electrical engineering and conveyor technology with – at the same time – increased requirements in explosion protection.
