Electrostatically dissipative components, smart textiles, among other beneficiaries.

Kraiburg TPE is now supplying electrically conductive TPEs that exhibit adhesion towards polyolefins and polyamides. Applications such as sensors for the automotive industry, electrostatically dissipative components, or smart textiles for sportswear and safety clothes require materials with defined electrical properties. Electrically conductive TPEs open up new opportunities for this type of application with regard to touch qualities, functionality and design.

Kraiburg TPE offers two new series of conductive TPEs to serve this emerging market. The EC series with adhesion to polypropylene (PP) provides a resistance of <101 Ωcm, a hardness of 70–80 Shore A, with a density of 0.97–0.99 g/cm3. The unique EC/PA series with adhesion to polyamides has a resistance of <103 Ωcm and a hardness of 70–80 Shore A, with a density of 0.96–0.97 g/cm3. Both products are available in black.

Besides electrical conductivity, the grades offer thermoplastic processability, a non-sticky surface feel, the ability to realize sealed and homogeneous surfaces, and the option of using multicomponent injection molding processes.

“The functional requirements for TPEs are steadily increasing. Following thorough testing, we have extended our portfolio to include electrically conductive TPEs in order to serve customers from a single source both now and in the future," summarizes Dr. Johannes Krückel, Key Account Manager at Kraiburg TPE. “We will continue to provide for the classic areas of application, but there’s a clear trend towards new additional applications. We’re therefore expecting electrically conductive TPEs to play an important role in tomorrow’s market and we’re pleased to be able to provide our customers with consistent product quality, along with the usual excellent service for these products as well.”
