PLA grade targets styrenics applications

There's a new grade of polylactic acid (PLA) on the block, and it has consumer goods currently molded from GPPS, SAN, HIPS and ABS in its sights. The new grade, dubbed Ingeo 3251D, is an improved injection molding grade of the Ingeo plant sugar-based plastics supplied by NatureWorks LLC (Minnetonka, MN), a joint venture of Cargill and Teijin Ltd.

This material was designed specifically for the consumer goods segments such as electronics, cosmetics, housewares, toys and custom molding. According to the supplier and compared to its established injection molding grade, the new grade improves productivity via shorter molding cycles, and it can be processed using the same mold and plasticizing screw as used with GPPS, SAN, HIPS and ABS. NatureWorks also anticipates some injection molders will see potential for down gauging in some applications as well as possible energy savings.

Targeted are semi-durable applications that are either clear or opaque; are currently molded in GPPS, HIPS, SAN, ABS or PET; and require impact resistance similar to medium impact polystyrene.[email protected]
