Hickman says Dow Chemical made recent advances in impact modifiers for packaging applications using corn plant material. Teaming up with PolyOne Corporation, Dow Chemical introduced OnCap BIO L, a bio-based polymer impact modifier designed to improve the impact resistance of opaque, injection-molded polylactic acid products. “It’s made from corn, but it could be made from other things,” says Hickman. “It would be nice to make it out of saw grass, and there’s a big move to do that, too. There’s also a move afoot attempting to use wheat stalk to create polymers,” says Hickman.
