GENERAL PROPERTIESDuratron® Polyimide is a high performance amorphous (non-crystalline) engineering thermoplastic. Chemically, Duratron® is a fully imidized thermoset polyimide.
NOTE: The Duratron grades listed on this page have been replaced with newer products. Limited existing inventory remains and is available until sold off. See Duratron Polyimide Product Family for detailed descriptions.
Duratron® Polyimide is well suited for structural and electrical applications where maintaining purity or electrical insulation is critical. Duratron® PI is synthesized differently than competitive polyimides resulting in improved chemical resistance, lower coefficient of thermal expansion and significantly better physical properties, including heat resistance to 575°F (300°C).
FEATURES Lowest wear rates and highest PV capability Lowest wear to mating surfaces Higher hardness than other polyimides Lower thermal expansion than other polyimides Better chemical resistance High purity levels
DURATRON GRADESDuratron® XP (Unfilled) : DISCONTINUED - replaced by Duratron D7000 PI
Duratron® XP replaced the previous grade Duratron® HP, which is no longer available. Duratron® XP was developed to compete with other high-purity polyimides, such as Vespel® SP-1.
Duratron® XP contains less than 1 ppm of metallic impurities as measured using the ICP-MS test standard. This purity is comparable to other commercially available polyimide shapes. As a result, Duratron® XP is ideal for using in high-energy gas plasma etch and strip processes. It is resistant to most gas plasma formulations using in semiconductor processing and meets or exceeds the performance of other polimides.
Duratron® XP has higher tensile and compressive strengths, higher impact strength, and lower water absorption than the now-obsolete Duratron® HP. The high temperature capability and purity of Duratron® XP make it especially well-suited for applications in the clean room, including wafer rings, wand tips and wafer handling tools.
Duratron® 150 (15% Graphite Filled) : DISCONTINUED - replaced by Duratron D7015G PI
Duratron® 150 polyimide contains 15% graphite lubricant. It offers the best combination of physical properties and toughness among lubricated polyimide grades. Duratron® 150 is an excellent material for bearings, slides, and high temperature wear applications.
