New jacket compounds for flexibility and safety in data centres

and data transfer capabilities is truly an accomplishment. These new compounds enhance cable performance, ensure fire safety and allow for uninterrupted data transmission in the most demanding environments.” Orbia Alphagary offers a range of compounds, including non-halogen Megolon and PVC-based Smokeguard formulations, to meet diverse application needs and to adhere to environmental and regulatory requirements. Santiago Urbina, VP commercial for Orbia Polymer Solutions (Alphagary), commented, “Our customers continue to seek jacket materials that meet heightened requirements for safety and performance in their data centre cable manufacturing operations. Our investment in R&D allows us to achieve both ends and continuously optimise our solutions to meet our customers’ needs, with no compromises.” Orbia Polymer Solutions (Alphagary) www.alphagary.com

In response to the demand for data centres driven by the expansion of artificial intelligence (AI) applications, Orbia Polymer Solutions (Alphagary), a provider of compounds and materials, has launched jacketing compounds engineered to optimise the safety and performance of data centre cables. Backed by research and testing to achieve optimal mechanical and flame-retardant performance, Orbia Alphagary has developed compounds that withstand high levels of fire testing – including the European CPR B2ca standard and the US NEC plenum standard – all while maintaining data transfer capabilities. The compounds are also formulated for enhanced flexibility, to aid installers who need to fit cables in confined areas. “The compounds developed by Orbia Alphagary represent a significant leap forward,” said strategic marketing director LeeAnn Chen. “Formulating a jacket compound to be flexible while still achieving high fire performance

Permanent printing on soft PVC The wear-resistant marking of products made of soft PVC, such as strands, cables, sheathed cables, pipes, hoses and profiles, presents a challenge to the cable and extrusion industry. Printer specialist Leibinger has developed an ink that is resistant to plasticisers and also prevents the transfer of printing ink to neighbouring cables. The extruded products being considered primarily comprise polyvinyl chloride (PVC). Depending on the application, they are mixed with plasticisers, also known as softeners. After production, the printed cables are usually coiled onto reels. Due to “plasticiser migration”, an imprint or “transfer print” may appear on the neighbouring cable when it is being unwound at a later date. To prevent this, Leibinger has a specialist ink for use on PVC.

Customized Solutions

To mark materials reliably, the printer technology and the printer ink need to be well matched. To help achieve this, Leibinger develops and produces its own inks, including a special black ink for the printing of extruded products. Leibinger has developed an ink for marking extruded goods

The ink was developed to adhere reliably to PVC materials for the cable marking and metre marking of extruded goods. It is resistant to plasticisers, and so prevents accidental transfer prints. With a Blue Wool Scale (BWS) ranking of eight, it also possesses high UV stability. This is particularly important, for example, when used on window spacers. In addition, the ink dries very quickly, making it suitable for high-speed applications. Paul Leibinger GmbH & Co KG www.leibinger-group.com
