Impact-modified PLA compounds

The company’s line of polylactic acid (PLA) bioplastic compounds has been expanded to include impact-modified grades suitable for select semidurable and durable applications. The compounds offer enhanced impact strength and higher heat-deflection temperatures than are possible with unmodified PLA resin.

Available in both injection and extrusion grades, the new materials also include impact modified, nucleated, and mineral-reinforced compounds. Varying levels of impact modification are available. The compounds are available in both opaque and translucent versions and can also incorporate FDA-compliant ingredients.
