These facilities are equipped with state-of-the-art analytical, synthesis, polymer characterization and testing equipment, along with pilot plants and polymer manufacturing operations that simulate specific production processes. The new lab and plant will conduct cutting edge chemistry testing and evaluations to help customers tackle and overcome the challenge of plastics recycling and the goal of a circular economy. Avient will use this data to develop new and unique masterbatch formulations with proven science behind how they perform during recycling processes, offering customers a portfolio that’s essentially field-tested for recycling.
