Parkinson Technologies Inc., Woonsocket, R.I., teamed up with Solvay Solexis, Inc., Thorofare, N.J., to produce what’s believed to be the first biaxially oriented PVDF film. The film was produced in Parkinson’s Marshall & Williams extrusion and orientation lab facility in Woonsocket for a Solvay project whose details are confidential.
The project was a year in the making, and involved numerous changes to both process settings and hardware to accommodate the resin’s narrow processing window. “With PVDF, the range of temperatures and stretch ratios was much narrower than typical commodity resins, making it more difficult to identify the process window and making the overall manufacturing process less stable,” explains Ken Forziati, Parkinson’s business development manager. “This was complicated by the 16-micron finished film thickness. When process conditions fall outside the process window, the material typically breaks in the MDO or splits in the TDO, making nothing but a lot of very expensive scrap.” Forziati added that processing PVDF also required corrosion-resistant hardware for the extruder, melt pipes, die, etc.
Biax PVDF film boasts unique properties, including abrasion and corrosion resistance, that suit it to a wide variety of applications in harsh environments, such as capacitors. (401) 762-2100 • parkinsontechnologies.com
