Polyimide filled PTFE is used to improve the creep resistance of PTFE. It is widely used for rod packing, rider– and piston rings in compressor applications. Fluorolon 1058 has been approved in “bone dry” gas compressors as a piston and rider ring. *Note Fluorolon 1058 supersedes Fluorolon 1310.

APPLICATIONS:

Polyimide filled PTFE is ideal for high wear applications, against high hardness surfaces. Examples of major applications are: Gliding elements in weaving machines, compressor rings in pumps and dry gas compressors. Excellent in high speed rotary sealing service. Can be used in both medium and hard mating surfaces.
