Most plastics have very low electrical conductivity and therefore display a strong tendency to accumulate charges which gather on the surface through contact with other materials. The resulting surface charges often have problematic effects.
“In order to prevent plastic parts from attracting dust particles through their electrostatic charges, for example in vehicle interiors, we have been developing new antistatic materials with improved properties”, says Dr. Jan Stadermann, project manager at the GRAFE Group. In our work we have already tested and analyzed new products based on different methods. Further development in the field of migrating antistatic agents has mainly been aimed at prolonging their effect. To this end, the GRAFE Group has introduced a new product for polyolefins: the High Performance Antistatic Agent (HPAS), which in long-term tests with PP components, has shown to be effective for more than 4 years.
In the development of permanently effective non-migrating systems, the focus lies on improving their efficiency. New permanently antistatic agents have been developed and tested for application in PP and in PC/ASA. These products are characterized in particular by lower concentration levels. In addition, combination products have been developed for application in PP and in PC/ASA where the material is colored and endowed with permanently antistatic properties in just one step.
