New Biobased PHA copolymers from Metabolix significantly improve performance characteristics of PVC [Registered]

The US startup Metabolix, recently announced that its 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 tonnes per year. 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…
