Asahi Kasei develops PFAS-free PA66 for demanding low-friction applications

In response to the tightening global regulations on per- and polyfluoroalkyl substances (PFAS) across the European Union and the United States, Asahi Kasei has developed a new PFAS-free polyamide (PA) 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.

The new PFAS-free LEONA PA66 exhibits excellent low-friction and sliding properties, which are crucial for applications where lubrication with oil or grease is not possible. It maintains stable performance under high-load and high-temperature conditions.

These features 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, Asahi Kasei offers PFAS-free PA 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, Asahi Kasei 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.
