Asahi Kasei is proud to offer an extensive lineup of LEONA™ polyamide resin grades that feature a variety of blends with fillers and other additives.

The core lineup of LEONA™ PA66 resins offers an extensive range of options tailored to specific needs: from standard formulations to glass-fiber (GF) reinforced, low-warp and low-abrasion, impact-resistant, high-viscosity and fatigue-resistant, friction-friendly, heat-resistant, flame-retardant options, and more.

In addition to our comprehensive PA66 offerings, we also provide specialized blends like PA66/6I, which incorporates semi-aromatic polyamide 6I, as well as 66+6I polymer alloys. For environmentally friendly or specialized solutions, we offer grades derived from low-water absorption PA612 and plant-based PA610, which also features low water absorption.
