properties vary considerably depending on the requirement. Orion operates four different tech- nologies to produce it, with each process allowing us to offer carbon blacks with singular properties [catering to] the specific needs of our customers.” He said: “The production of acetylene black stands out [because] it uses acetylene gas as feedstock, generating a conductive additive that offers the highest purity, delivers excellent disper- sion and surface smoothness, as well as high conductivity. These properties make the use of acetylene black invaluable in semiconductive layers. Most modern MV, HV and EHV cables have addi- tional internal layers in the insulation system to control the electric field around the conductor to ensure more efficient power transmission. They also protect the insulation from electric discharges ensuring longevity of the cable. The compounds used for the semiconductive layers contain specially engineered grades of carbon black to ensure consistent conductivity at elevated temperatures. Due to its excellent dispersibility in the polymer matrix, acetylene black delivers exceptionally smooth surfaces, which is important as it decreases the occurrence of regions of high electrical stress.”
Future thinking On the future of the sector, LeeAnn Chen, Global Product Director Orbia Polymer Solutions (Alphagary), said: “The rapid growth of 5G infra- structure and AI is prompting wire and cable companies to reshape supply chains. Companies are adopting strategies such as nearshoring and friendshoring, as well as building new facilities in locations where demand for wire and cable is growing. As data centres expand to meet the demands of data transfer and network perfor- mance, cable materials play a critical role. As a materials designer, Orbia Alphagary is creating technological advancements in high-performance cable jacket materials to provide optimised
solutions that balance complex properties. De- mand for renewable energy, energy from nuclear power, and AI-driven applications, is accelerating advancements [and] increasing the need for highly specialised, durable and high-performance materials. Cable jacketing must withstand extreme environmental conditions, resist radiation, and exposure to oils and chemicals, all while remaining flexible, easy to process, and preserving signal integrity. These advanced materials are essential for supporting the next generation of energy and technology infrastructure.” Marcus Hohlweck, Head of the Industrial
Compounding business segment at Melos, agreed: “The future of the cable market will continue to be characterised by technological advances and increasing regulatory requirements. Companies that focus on sustainable, high-performance materials at an early stage and react flexibly to market require- ments will be successful in the long term.” Reference (1): The Insight Partners Benvic’s view is that “there is no doubt that cable compounds face a rapidly growing market with many factors and niches. However, progress is dependent on disruptive evolution and meeting the needs of fast-changing industries and infra- structures across many international barriers”.
