The Bioplastics Div.of MGP Ingredients, Inc., Atchinson, Kan., has expanded its portfolio of Terratek renewable-content plastics with a new line of biodegradable compounds. Terratek BD 4015 is a proprietary blend of natural and synthetic biodegradable resins, based on wheat, corn, and other compostable materials. Natural components derived from renewable grain sources reportedly make up the majority of the resins’ content by weight. Terratek BD is said to be fully compostable.

Mike Parker, bioplastics product development and sales manager, says this resin’s unique advantages include higher heat tolerance (up to 400 F) than similar products. “We view this as a significant breakthrough,” says Parker. The resin also boasts excellent mechanical properties, including a rare combination of rigidity and pliability. It has a density of 1.30 g/cc, melt flow of 8.8 g/10 min, notched Izod impact strength of 0.93 ft-lb/in., and tensile strength of 2700 psi. Targeted applications include injection molded disposable packaging.

MGP Ingredients started up its biobased plastics business in 2006. The company’s other plastic offerings include Terratek SC 50 and 65, proprietary blends of 50% and 65% wheat starch and PP for injection molding. Also, Terratek WC 100300 is a blend of 30% pine wood fiber and recycled PP for injection molding. A range of properties can be achieved by altering the wood/plastic ratio and additive content. Formulations containing anywhere from 30% to 60% wood fiber are available on request.
