Director for Global Marketing – Poly- mer Systems at Orion. “Printex kappa 105 is produced with a novel technol- ogy ensuring exceptional purity levels and a considerably lower carbon footprint, if compared to regular carbon black.” Impact strength of Printex kappa 105 is maintained after aging at 140° C. The compound with acetylene black withstands deterioration better than a PP with regular furnace black, Orion reported.
Orion continues to finish the construction and commissioning of its LaPorte, Texas, plant that will provide an additional 1,200 tonnes of acety- lene-based carbon black to North American markets. The plant is expected to open in 2026. The company noted that it wants to support “local production for local consump- tion,” with its plants in France and Germany and the new facility in the US. “Electrification of the automotive
powertrain and the ever-increasing importance of electronics in daily life keep creating new demands on conductive plastics,” said Alexandra Megally, who is Marketing, Strategy and Sustainability Manager, EMEA region, Cabot Corporation. “Many of those [demands] can be addressed by tweaks and reformulation with existing additives, but we certainly see an increasing number of requests for conductive carbon blacks with special features – extra conductive,
high purity, reduced interactions, and a combination of those.” New from Cabot is Vulcan XCmax
55 extra conductive carbon black, which combines the benefits of the Vulcan XCmax series with the benefits of low interaction with other ingredi- ents in the formulation. “Vulcan XCmax 55 offers conductivity at around half of the loadings of typical conductive carbon blacks, resulting in increased formulation freedom and better mechanical performance of final parts,” reported Megally. “[The product also] offers reduced interactions with other ingredients in the formulation, which then, among a broad range of potential benefits, can lead to better flowability of the plastic compound and allowing other additives to better unveil their full potential.” Megally sees growing demand for conductive thermoplastic compounds in cable industries, where growth is driven by renewable energy expansion and digital transformation. “In the cable industry, global investments in renewable energy, grid modernisation, and electrification are driving the need for reliable cables capable of manag- ing increased electricity demand and bidirectional energy flow. Conductive compounds play a critical role in these applications, offering solutions for energy transfer, grounding, and shielding,” she explained. Industrial packaging is another important industry, where the
