system design, without compromising durability. “This marks a breakthrough in HVDC insulation capability, as we apply our deep expertise in
cross-linked polyethylene to help customers meet evolving HVDC requirements,” said Edit Berczi, Wire & Cable global marketing manager, Packag- ing & Specialty Plastics, Dow.
Carbon black Carbon black remains a critical component in wire and cable, contributing to electrical conductivity, UV protection, mechanical durability, and long term aging resistance. Compounded solutions play a key role in meeting these requirements, enabling material suppliers to support customers in balanc- ing conductivity, mechanical performance, and processability, particularly in semiconductive layers, insulation, and jacketing systems. Recently, Cabot launched Vulcan XCmax 55 extra conductive carbon black. “This advancement meets industry demands for
improved energy efficiency, optimised material usage, and more sustainable cable designs,” said Alexandra Megally, marketing, strategy, and sustainability manager, EMEA region, Cabot. “It is
particularly well suited for conductive plastics requiring low loadings and low interactions, helping manufacturers control viscosity increases, maintain processability, and prevent negative interactions with other additives. Looking ahead, resilience and consistency will remain central themes for the wire and cable industry. As power and data networks become ever more critical to societies and economies, expectations around quality, traceability, and long-term reliability, will continue to rise.”
Acetylene black has gained momentum due to its unique combination of exceptionally high purity, very high conductivity, and excellent dispersibility in polymer matrices, properties which support the formation of uniform conductive networks at controlled loadings and enable ultra smooth semiconductive layers, an essential factor in minimising localised electrical stress at the inter- face with insulation. These performance advan- tages are reflected in the solid progress being made with approvals at major cable manufacturers. Compounds incorporating acetylene black have demonstrated consistent conductivity at elevated temperatures, stable extrusion behaviour, and
