Asahi Kasei develops the high-performance PFAS-Free PA66
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. Asahi Kasei’s 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, 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.
Utilising its unique processing control technology, Asahi Kasei can further tailor the material’s performance profile. Customised formulations can optimise filler content, heat resistance, stiffness, and behaviour under wet conditions, providing design flexibility that helps customers transition smoothly to PFAS-free solutions without sacrificing product performance.
“As industries around the world move away from PFAS, we see a strong need for materials that go beyond compliance and actually raise the bar for durability and efficiency,” said Yoshitaka Hori, Senior General Manager of Asahi Kasei's LEONA PA66 business. “Our new PFAS-free PA delivers exactly that, and we are excited to support our customers in building safer, more sustainable products.”
