This nylon 66 material offers a higher mechanical strength, stiffness, heat and wear resistance than its nylon 6 counterpart. It also has a better creep resistance but its impact strength and mechanical damping ability are reduced. Well suited for machining on automatic lathes. Please note that Nylatron® 101 / Ertalon 66 SA natural rods over dia. 150 mm are made from a modified polyamide 66 resin.
