Portfolio expansion at GRAFE Polymer Technik: Electrically conductive compounds and functional compounds

The GRAFE Polymer Technik is specialized in the modification of thermoplastics for electrically conductive carbon black composites. This year at the FAKUMA trade fair it is presenting many new developments in its extensive product portfolio, as well as the latest edition of its product brochure.

The GRAFE Group offers an extensive range of electrically conductive compounds which are in part available in different colors (COLORSTAT Series PP, LDPE, ABS and Soft). Product innovations include new types of electrically conductive PS, ABS, SBC as well as type improvements in PPL3 and PPL6 quality, in addition to the already well-known materials for production of storage and transport boxes, containers for chemical equipment manufacturing, hoses and pipes and packaging for electronic parts. The mechanical properties of the polypropylene and ABS-based colored conductive materials of the Colorstat® range have been improved and the range of possible colors expanded. The new color-neutral electrically conductive Colorstat® PO and PA Soft makes it possible to produce color-specific polyolefin and polyamide-based technical soft parts. GRAFE has also developed new and more efficient PP EC types which are outstanding, particularly in the highly conductive sector, with maximum requirements for flow and mechanical properties. „These types are ideally suited for electrically conductive pipette tips in medical and analytical technology and for thin-walled components,“ says Steffen Felzer, Managing Director of GRAFE Polymer Technik GmbH. Specialized biopolymer, thermally conductive and ferromagnetic compounds continue to gain importance in the complete product portfolio of the GRAFE Polymer Technik GmbH.


„Our corporate philosophy is focused on research and development for the future with a maximum level of customer proximity,“ continues Steffen Felzer. „For our customers that means we develop and produce according to their individual needs. That applies to all functional compound solutions. As a result, our product portfolio includes a growing number of thermally conductive, ferromagnetic, matting, light, heavy, haptic, flame-retardant and general additive compounds in addition to the electrically conductive materials. Of particular interest is a PP film quality with matting properties on the material side.“


„One of our top aims has been to produce low emission carbon black compounds. Many polycyclic aromatic hydrocarbons (PAC) have been proven to be carcinogenic and are absorbed through skin contact, food or by breathing affected air. Standardized testing procedures in accordance with the GS certification have been introduced to evaluate the danger of PAC to consumers. A binding EU regulation (1272/2013) limiting the maximum PAC concentration in many products to 1mg/kg will be in effect from December 2015,“ says Steffen Felzer. „We have succeeded in adjusting the ingredients in our formulation so that we can produce electrically conductive compounds also with reduced PAC. We have also been able to develop different types of >PPEC FR<. The types we have developed achieve the UL94 V-0 Class at 1.6mm.“


„We will be presenting our new product brochure with GRAFE Polymer Technik’s entire portfolio for the first time at the FAKUMA. With the new design our customers will be able to see at a glance our complete range of products and extensive service offer.”
