PI

Overview

The various properties of Duratron PI provide excellent performance in applications requiring wear resistance and long service life in harsh environments. Duratron PI is an ideal choice for applications that exclude the thermal requirements of Duratron PAI and do not require the exceptional heat resistance of Duratron CU60 PBI. As a result, Duratron PI components can be used in highly demanding applications across industries such as automotive, aerospace, aviation, defense, electrical, glass, nuclear, and semiconductors.

Properties

• Extremely high allowable continuous use temperature in air [240°C continuously, up to 450°C for short durations]
• Excellent ability to maintain mechanical strength and creep resistance across a wide temperature range
• Superior sliding properties and outstanding wear resistance
• Inherently low flammability
• Excellent electrical insulation and dielectric properties [applies to Duratron D7000 PI only]
• Low outgassing under vacuum conditions [dry material]
• High purity in terms of ionic contamination [Duratron D7000 PI]
• Excellent resistance to high-energy radiation

Applications

Valves, pump seats, seals, wear surfaces used in semiconductor and electronics manufacturing; structural and wear parts; jigs and transport components used in glass and plastic manufacturing; metal replacements in aerospace components.

Grades

Duratron PI is available in several grades for structural and wear applications and can be used in a wide range of forms, especially in thick sheet form, large geometrically structured plates, and large-diameter tubes.

Duratron D7045G PI [PI + Graphite; Color: Dark Grey]
This grade contains 15% graphite, added to enhance wear and friction resistance.

Duratron D7000 PI [PI; Color: Standard Grade (Brown)]
The base grade of the Duratron PI product family, made from natural polyimide resin, offering top physical properties and excellent electrical and thermal insulation performance.
