PA – Polyamide
PA 6 G
PA 6 G is a cast polyamide that combines great mechanical strength, stiffness, hardness, and elongation potential with good sliding characteristics. PA 6 G has better mechanical properties than extruded polyamide. We deliver PA 6 G as plastic sheets and rods and as hollow rods.
