Advanced Engineering Plastics <strong>for</strong> Elevated Temperature Range<br />
Duratron ® PI<br />
Polyimide [PI]<br />
Duratron PI offers a combination of properties that allows it to excel in applications requiring low wear and long<br />
life in harsh environments. Duratron PI is an exceptional value <strong>for</strong> applications where thermal requirements<br />
exclude Duratron PAI and do not require the extraordinary thermal resistance of Duratron CU60 PBI.<br />
Consequently, Duratron PI parts are put to use <strong>for</strong> very demanding applications in the automotive, aerospace,<br />
aviation, defence, electrical, glass, nuclear and semiconductor industries.<br />
Main Characteristics<br />
Extremely high max. allowable service temperature in air [240 °C continuously, with short term excursions<br />
up to 450 °C]<br />
Excellent retention of mechanical strength, stiffness and creep resistance over a wide range of<br />
temperatures<br />
Good sliding properties and excellent wear resistance<br />
Very good dimensional stability<br />
Inherent low fl ammability<br />
Good electrical insulating and dielectric properties [only applies to Duratron D7000 PI]<br />
Low outgassing in vacuum [dry material]<br />
High purity in terms of ionic contamination [Duratron D7000 PI]<br />
Excellent resistance against high energy radiation<br />
Applications<br />
Valve and pump seats, seals and wear surfaces, structural and wear parts <strong>for</strong> semiconductor and electronics<br />
manufacturing, fi xtures and handling parts <strong>for</strong> glass and plastics manufacturing, metal replacement <strong>for</strong><br />
aerospace components.<br />
Grades<br />
Duratron PI is available in several grades <strong>for</strong> structural and wear applications and in the broadest range of<br />
shapes - particularly thick sheets, larger sheets geometries and heavy-wall tubes.<br />
Duratron ® D7000 PI [PI; colour: natural (chestnut)]<br />
Duratron D7000 PI - the basic grade within the Duratron PI family - is made from unfi lled polyimide resin and<br />
provides maximum physical properties and best electrical and thermal insulation.<br />
Duratron ® D7015G PI [PI + graphite; colour: grey-black]<br />
This grade contains 15 % graphite, added to provide long wear and low friction.<br />
