A new PFAS-free polyamide (PA) has been engineered specifically for demanding low-friction applications. For decades, PFAS additives have been relied upon to deliver low friction and wear resistance in engineering plastics. As regulatory pressure intensifies, industries ranging from automotive to industrial machinery are seeking alternative solutions. This newly developed PFAS-free PA addresses this shift by combining environmental responsibility with the advanced material performance required for next-generation components. The new PA exhibits excellent low-friction and sliding properties—crucial for applications where lubrication with oil or grease is not possible. It maintains stable performance under high-load and high-temperature conditions. These characteristics make it ideal for mechanical parts such as gears, chain guides and other sliding components that must operate reliably in dry environments. To meet the diverse needs of manufacturers worldwide, the PFAS-free PA is offered in both unreinforced and reinforced grades. These options allow engineers to select the optimal balance of strength, stiffness, and durability for their specific applications. Utilizing its unique processing control technology, the manufactuer can further tailor the material’s performance profile. Customized formulations can optimize filler content, heat resistance, stiffness and behavior under wet conditions — providing design flexibility that helps customers transition smoothly to PFAS-free solutions without sacrificing product performance. — Asahi Kasei Corp., Tokyo, Japan
