BASF enters the long glass-fiber-reinforced polyamide market
BASF is entering the market with a new class of high-performance polyamides in the K-year of 2010 and presenting its first long glass-fiber-reinforced (LF) polyamide grade Ultramid® Structure LF. This product group which is new in BASF’s portfolio, represents a considerable advance in terms of performance with metal substitution as the objective, since where even highly optimized short glass fiber-reinforced products reach their limitations, LF polyamides offer new opportunities. Production of LF resins employs the pultrusion process to first create plastic strands containing endless glass fibers. In a second step, these strands are cut to a pellet length of 12 millimeters. The customer can process the LF granules on a conventional injection molding machine. With a favorable distribution of fibers in the molded plastic part, a three-dimensional fiber network of primarily three to six millimeters long fibers is formed directly without any significant additional effort. Processors can avoid major investment costs, and still gain access to a new sophisticated material: Compared to classical reinforced polyamides with their only 0.3 millimeters long fibers, entirely new component characteristics are achieved. The exceptional component properties come from the enhanced mechanical capabilities brought about by the long glass-fibers: the LF polyamide grades Ultramid Structure are very stiff and strong at elevated temperatures, while at low temperatures they exhibit outstanding impact strength. Impressive creep behavior, the minimal warpage and the far higher energy absorption – and thus crash performance – compared to conventional materials are further benefits.
