GENERAL DESCRIPTIONDuratron ® 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 D7015G PI (15% Graphite Filled)
Duratron ® D7015G PI is 15% graphite-filled polyimide and is designed for use in high-temperature bearing and wear applications, including bushings, bearings, slides, wear strips, valve seats, and high speed pump and compressor parts.
Duratron ® D7015G PI is available molded plates/sheets, rods, and tubes of relatively short lengths. Check with us for availability of D7015G PI in the size you need. (see also Vespel® SP-21 and Plavis G15)
