Envalior, a global engineering plastics specialist, unveiled high-performance material solutions for AI data center power infrastructure and cooling systems at Fakuma 2026, held in Friedrichshafen, Germany, from October 12 to 16. As increasing AI computing workloads raise data center power density and operating temperatures, materials with heat resistance, electrical safety and dimensional stability are becoming more important. In particular, the transition to 800V direct-current (DC) power infrastructure requires specialized material solutions for high-voltage environments. Envalior introduced Stanyl® PA46, Pocan® PBT and ForTii® PA4T PPA as materials for power infrastructure. Stanyl® CR310 PA46 supports arc extinction in switchgear operating in DC environments, where interrupting an arc is more difficult than with alternating current. Its heat deflection temperature, HDT(A), is 290°C, higher than that of conventional PA66. Pocan® PBT is used in 800V DC connectors because of its high tracking resistance, with a comparative tracking index (CTI) of 600. ForTii® C11F PA4T PPA is an injection-moldable material for switchgear housings that maintains strong mechanical properties at high temperatures. The company also showcased busbar connectors made using Akulon® PA66, Pocan® PBT and Xytron™ PPS, as well as TÜV-certified board connectors based on ForTii® T11 PPA. For cooling systems, it presented Xytron™ PPS, which offers high heat resistance and dimensional stability. Applications range from cooling fan blades and housings to liquid-cooling components at the server and rack level. Its corrosion resistance and low ion leaching help maintain coolant electrical conductivity and reduce maintenance requirements. Ultrathin cooling fan stator insulation made with Stanyl® PA46 also supports more powerful cooling by enabling high torque density. Martin Burg, an advanced development specialist at Envalior, explained that higher data center voltages require materials with high tracking resistance, heat resistance and dimensional stability at elevated temperatures. Burg said responding to the transition to 800V DC power infrastructure requires specialized material solutions that account for the mechanical, thermal and electrical properties of individual components. Envalior also introduced 360 Innovation Services, which supports material selection, design, testing, simulation and production optimization. Using CAE modeling and AI-based tools, the service helps customers shorten product development times and reduce mass-production risks and costs. John Hsieh, segment innovation manager for electronics at Envalior, emphasized the importance of material design that comprehensively considers the roles of data center components, alongside production scalability. Hsieh explained that the company's global production and research and development network helps optimize component-specific performance requirements and supply chains while supporting long-term reliability.
