GENERAL DESCRIPTION
Duratron ® D7000 series machinable polyimide is an exceptional value for applications where thermal requirements exclude Duratron T PAI and do not require the extraordinary thermal resistance of Duratron PBI. Duratron PI is available in several grades for structural and wear applications and in the broadest range of shapes - particularly thick sheets, larger sheet geometries and heavy-wall tubes.
Duratron PI machinable shapes are ideal starting points for designs that reduce weight, extend length of service before maintenance or replacement and reduce overall cost by increasing process uptime.
Duratron D7000 PI (Unfilled)
Duratron ® D7000 PI is unfilled polyimide. The purity of unfilled Duratron® D7000 PI make it especially well-suited for applications in the clean room, including wafer rings, wand tips and wafer handling tools. Other common applications include test sockets, electrical connectors, spacers, terminal strips, and high-temperature insulators.
Duratron ® D7000 PI is available molded plates/sheets, rods, and tubes of relatively short lengths. Check with us for availability of D7000 PI in the size you need. (see also Vespel® SP-1 and Plavis N)
See also Duratron D7015G PI specification for comparison, or these two polyimide grades side-by-side here.
