Two additive suppliers have expanded their offerings of modifiers for polylactic acid (PLA) biopolymers: •Biomax Thermal 300, a proprietary heatdistortion modifi er from DuPont Packaging and Industrial Polymers, Wilmington, Del., is said to allow PLA thermoformed packaging to withstand up to 95 C/203 F during transport, storage, and use. It contains 50% renewably sourced content and is FDA compliant for food contact. Biomax Thermal 300 extends PLA’s use beyond chilled-storage food packaging. At use levels of 2% to 4%, it is said to have minimal effect on clarity and to accelerate thermoforming cycles. •Biostrength 900 metal-release lubricant from Arkema Inc., Philadelphia, is an acrylic copolymer that is said to enable more consistent processing of PLA. Use levels of 1% to 5% reportedly permit a wider processing window and lower scrap rates in injection molding and calendering. (800) 628-6208 • www.dupont.com (215) 419-7000 • www.arkema.com
