DuPont Fluoroproducts has announced the introduction of a new grade of permeation resistant DuPont™ Teflon® PFA HP Plus. The new resin, Teflon® PFA 951HP Plus, is designed for molding and extrusion for fluid handling components and tubing, and cuts hydrochloric acid (HCl) permeation by up to 40 percent to ensure durability and longer life, lowering the cost of equipment ownership for semiconductor manufacturers. This is the latest in the Teflon® HP Plus line of polymers from DuPont Fluoroproducts, which offer high purity, chemical resistance and mechanical properties ideally suited to semiconductor manufacturing environments. Teflon® PFA 951HP Plus is part of a broad portfolio of semiconductor materials that DuPont will feature at Semicon West 2005, July 12 – 14 at the Moscone Center in San Francisco, Calif., at the DuPont Booth #2416, South Hall.

"What is so unique about this product is that it’s a patented innovation that controls permeation to an extremely high degree, which is increasingly critical as chip manufacturers move from aluminum to copper materials", said Mike Cardona, North America Semicon marketing manager. "This enables long-lasting, reliable operation of equipment even in today’s most demanding fluid handling environments, especially those involving HCl. We are pleased to introduce Teflon® PFA 951HP Plus at Semicon West. It’s another example of how DuPont is applying science and technology to advanced semiconductor materials."
