Envalior offers PFAS-free materials for wear and friction applications - The Robot Report

Envalior, a global leader in engineering materials formed in 2023 by merging Lanxess Performance Materials and DSM Engineering Materials, is addressing the growing demand for PFAS-free alternatives in high-wear and high-friction applications such as robot actuation. Recognizing the regulatory and health concerns surrounding per- and polyfluoroalkyl substances (PFAS), including PTFE, Envalior has developed high-performance materials that do not rely on these "forever chemicals." Their Stanyl polyamide 46 (PA46) compounds offer a sustainable, economical, and durable solution for components like timing systems, actuator gears, bearings, seals, and bushings, meeting stringent performance and legal requirements without PTFE additives. Stanyl PA46 stands out due to its high crystallinity, providing superior fatigue and wear resistance, impact strength, excellent flow for thin-walled designs, and outstanding stiffness and creep resistance at elevated temperatures. These properties make it suitable for demanding applications involving high torque, speed,
