Two new SMA copolymers are claimed to offer up to 60% greater toughness than traditional grades. Dylark 510XT and 520XT from Nova Chemicals Corp., Moon Township, Pa., provide enhanced stiffness and dimensional stability for auto interior parts. Higher impact protects finished products from rough handling, and the thin-wall capability results in significant weight savings versus other resins, the company claims. The high-impact grades are targeted for soft instrument panels, mid-consoles, cluster housings, knee bolsters, door modules, and interior trim.
