Cana BioProducts LLC has developed a plastics additive based on residual materials from ethanol production.
DDS Bio Composite can act as a chemical foaming agent and as a compatibilizer for blending different polymers, according to the Payson,
Cana BioProducts claims that when used in injection molding the new additive lowers part cost, cuts cycle time, provides lightweighting and adds an environmentally friendly aspect to a product. The biocomposite is a blend of a biopolymer, microfiber filler and fatty acids in a polar polymer carrier.
The additive generates carbon dioxide in the molding process to create a microcellular composite structure through an environmentally friendly foaming process. Resultant bubbles are only 1-50 microns in size and they surround individual particles. The nucleating action can reduce cycle time between 10 percent and 50 percent, Cana BioProducts claims.
An added benefit is the product's ability to eliminate the pack and hold phase of the molding cycle.
