WEB EXCLUSIVE: At the recent Fakuma 2011 show in Germany, BASF AG (U.S. office in Wyadotte, Mich.) introduced three new members of its “crash-optimized” nylon 6 family. They are Ultramid B3ZG7 CR (35% glass), B3ZG3 CR (15% glass), and B3ZG10 CR—the company’s first impact-modified nylon 6 with 50% glass fiber. Tougher than earlier CR grades, these are initially aimed at auto body parts for pedestrian protection but are also relevant for other energy-absorbing applications such as steering wheels, seats, or structural inserts. BASF developed a bending and torsion test specimen specifically for the CR grades. While the earlier grade, Ultramid B3WG6 CR (30% glass) can be twisted almost 150° without breaking in static torsion tests, the new grades withstand twisting up to 240° without damage.
