WEB EXCLUSIVE: Several new materials for automotive and electronics will be highlighted by BASF later this month at the Fakuma 2011 show in Germany. Among them are improved “crash-optimized” (CR) automotive grades of Ultramid nylon 6 with even better impact strength and wide range of stiffness and toughness. And for high-temperature automotive uses, new Ultrason E Dimension polyethersulfone combines dimensional stability, stiffness, and processability.
For electronics, new halogen-free Ultradur B4450G5 LS is an FR PBT with unusually high tracking resistance and UL 94V-0 certification at 1.5 mm wall thickness. Also new is Ultramid B3U30G6 halogen-free FR nylon 6 with increased stiffness for circuit breakers.
Exhibiting with BASF is its former Styrolution subsidiary, now an independent styrenic polymers joint venture (see above). For exterior, unpainted applications, Styrolution is introducing Luran S SPF30 ASA, whose new UV stabilization package reportedly offers a major improvement in colorfastness and surface quality. Gloss and color are retained considerably longer than by previous grades, suiting this material to front grilles, mirro housings, and spoilers.
Also new is Styrolution’s first ASA/nylon blend, called Terblend S NM-31. It combines toughness, good flow, and UV stability for rear shelves in cars, as well as lawn chairs.
