DURATRON XP... A NEW HIGH-PURITY, EASY-TO-MACHINE POLYIMIDE
Duratron XP is a high-purity, easy-to-machine polyimide ideal for components in semiconductor manufacturing and test equipment. Like other polyimides, Duratron XP has high strength and high heat resistance. Duratron XP polyimide stock shapes, including rod, bar and plate, can be easily machined to make dimensionally stable, structural parts designed for continuous use at temperatures up to 500 °F. Duratron XP has low levels of ionic impurities. All metallic impurities are controlled to be less than 1 ppm. Further, Duratron XP exhibits low outgassing when tested in accordance with ASTM E595: total material loss, after 24 hrs. at 125 °C and a vacuum of 10-5 mm Hg, is less than 1% and 0.00% collected volatile condensable material. Due to its low outgassing rates and low ionic impurities, Duratron XP is ideal for parts used in plasma etching chambers, such as locating rings, pedestals and frames. Duratron XP also has excellent chemical resistance. It is extremely resistant to aromatic hydrocarbons, acids and bases. Tests show that Duratron XP exhibits little or no loss of strength after prolonged exposure (100 hrs at 73 °F) in acetic acid, hydrochloric acid, phosphoric acid, nitric acid and sodium hydroxide. Other key benefits of Duratron XP are high strength and stiffness, high wear resistance, low friction and low creep. Compared to other high-heat resistant plastics, including other polyimides and polyamide-imides, Duratron HP has good machining characteristics. Duratron XP is a ductile polyimide and, as such, resists chipping, breakage and tool wear during machining. http://http://www.quadrantplastics.com
