Metabolix launches I6003rp, a new biobased performance additive to improve the processing and performance of recycled PVC
Metabolix, Inc. has announced the launch of I6003rp, a new biobased polymeric performance additive for recycled PVC (polyvinyl chloride). I6003rp demonstrates the value of excellent miscibility in PVC when used in combination with recycle PVC. This certified biobased process aid lowers processing torque and improves properties.
With increasing PVC waste coming from short-life products such as packaging, bottles and medical devices, as well as from long-life products such as pipes, window frames and cable insulation that have been in service for significant time and are increasingly being replaced, more PVC is entering the waste stream. "While PVC is one of the largest recycled polymers by volume, the amount of discarded post-industrial scrap and post-consumer waste that is actually recycled is still very low compared to the amount that is landfilled every year. Due to deterioration in physical properties when reprocessed, scrap PVC is downgraded and devalued," said Bob Engle, vice president, biopolymers, at Metabolix.
"I6003rp is a performance-driven additive that improves toughness and makes processing easier, enabling PVC converters to increase the rate of recycle use without compromising hardness. PVC Repro suppliers can upgrade the quality and value of Repro products," added Bob Engle.
Metabolix developed I6003rp based on data confirming that specific Metabolix grades of PHA (polyhydroxyalkanoate) have superb miscibility with PVC and enhance the processing and properties of recycled PVC. Dr. Yelena Kann, product development scientist at Metabolix, will be presenting this data at SPE Vinyltec 2013 being held October 21-23, 2013.
In 2012, Metabolix launched I6001, a biobased polymeric modifier for flexible and semi-rigid PVC that brings toughness, elongation and plastification without migration or compromising clarity. I6003rp represents an extension of the product line. With this process aid, Metabolix continues to drive advancements in the use of performance biopolymers for PVC manufacturing by harnessing the power of its innovative PHA-technology platform.
