Dyna-Purge Div. of Shuman Plastics, Inc., Depew, N.Y., has a new Dyna-Purge E2 purging compound for high-temperature thermoplastics. Dyna-Purge commissioned the Institute of Polymer Science and Polymer Engineering at the University of Akron, Ohio, to conduct an independent study of the material last December. Trials were conducted on a 55-ton Van Dorn injection press using polysulfone, polyetherimide (SABIC’s Ultem), and polyphthalamide (PPA). Dyna-Purge was found effective in purging all three materials cleanly. A copy of the study with complete results and trial protocol information is available from Dyna-Purge.
