Compound options Germany’s Lehvoss Group, which has been producing electrically conductive compounds for 40 years, continues to create new products specific to customers’ needs, says Thomas Collet, Director of Marketing for the Customised Polymer Materials business unit. The company added a new twin-screw extruder to its Innovation Center at Hamburg in Germany in August last year that is optimally configured for production of performance compounds such as the highly filled formulations required for electri- cally conductive and thermally conductive applica- tions. “The new lab machine is enabling us to
