Japanese chemical and polymer group Asahi Kasei (Tokyo; www.asahi-kasei.com) has announced the development of a PFAS-free polyamide 6.6 designed for low-friction applications under high loads, as manufacturers respond to tightening regulations on per- and polyfluoroalkyl substances in the European Union.

The company said the material, under the Leona brand and currently a development product, is intended to replace plastics that traditionally rely on PFAS additives to achieve low friction and wear resistance. According to the firm, it uses Asahi Kasei’s proprietary sliding technology to deliver properties comparable to those of fluororesins, while remaining compliant with emerging PFAS regulations.

Asahi Kasei said the polyamide maintains stable performance under high-load and high-temperature conditions, including applications where lubrication with oil or grease is not possible. Potential uses include gears, chain guides, and other sliding components operating in dry environments, as well as parts for automotive, aerospace and robotics applications, building materials, and sporting goods.

The PFAS-free PA6.6 is available in both unreinforced and reinforced grades, giving manufacturers flexibility in balancing strength, stiffness, and durability. The company added that further tailoring is possible through its processing control technology, allowing adjustments to properties such as heat resistance, filler content, and performance under wet conditions.
