Metabolix, Inc. (NASDAQ: MBLX), an innovation-driven bioscience company focused on delivering sustainable solutions for plastics, chemicals and energy, today announced that new biobased PHA (polyhydroxyalkanoate) copolymers significantly improve the mechanical and environmental performance characteristics of polyvinyl chloride (PVC). PVC is a polymer with a diverse use pattern ranging from construction materials to medical applications and an estimated global demand of approximately 35 million metric tons per year. Dr. Yelena Kann, Ph.D., senior polymer scientist at Metabolix, will present the findings in a presentation titled “New Biobased PHA Rubber Copolymers for PVC Modification” at the Society of Plastics Engineers’ Vinyltec 2012 conference on Wednesday, October 24, 2012. Metabolix developed a series of PHA copolymers and demonstrated that they were miscible with PVC resins. Based on miscibility and performance requirements, Metabolix researchers created specific compositions of PHA copolymers to improve plasticization, impact and processing modification of rigid and flexible PVC.
- In plasticization, PHA copolymers performed as high molecular weight, readily dispersible plasticizers and enabled formulation of compounds with low additive migration, low extractables, volatile loss and staining.
- In impact modification, PHA rubber copolymers outperformed the best available MBS core/shell impact modifiers and did not compromise PVC transparency or UV stability.
- As a processing aid, the metal-adhering properties of PHA copolymers promoted homogeneous shear melting of PVC particles and prevented overheating and degradation.
Metabolix worked closely with AlphaGary, a Massachusetts-based custom compounder of PVC and TPE/TPO materials, to validate PHA polymeric modifiers in PVC.“We are pleased with what we have seen in these new polymeric PVC modifiers and are beginning to test them in current high-value applications. They combine effective impact modification with good transparency and are made from renewable feedstocks,” said Mark Jozokos, global R&D manager at AlphaGary. “The introduction of new PHA products for use as modifiers in PVC is a significant step in Metabolix’s strategy for biopolymers that focuses on high-value applications,” noted Bob Engle, vice president business and commercial development, biopolymers at Metabolix. “We plan to manufacture these new PHA products in the 10KTPA facility that Metabolix is establishing at Antibioticos in Leon, Spain. We expect samples of the polymeric modifiers will be available to ship to customers from this facility in early 2013.” You can find more information about Dr. Kann’s presentation at Vinyltec here.
