PTFE Disk

Industrial Applications

PTFE Disc is used across chemical processing, electrical, mechanical, and research applications where precision circular geometry, chemical inertness, and reliable dielectric or tribological performance are required:

✦ Thrust Washers & Bearing Pads

Widely deployed as thrust washers and bearing pads in rotating equipment exposed to corrosive media, where PTFE Disc's low coefficient of friction of 0.05–0.2 and resistance to virtually all solvents and acids ensure reliable low-friction performance without lubrication in chemically aggressive service environments.

✦ Valve-Seat Inserts in Chemical Dosing Systems

Used as valve-seat inserts in chemical dosing systems where the precision circular geometry, chemical inertness, and dimensional accuracy of ±0.5 mm diameter tolerance provide accurate, repeatable seating interfaces resistant to the aggressive chemicals handled in dosing and metering applications.

✦ Dielectric Spacers & Standoffs

Applied as dielectric spacers and standoffs in high-voltage assemblies, where dielectric strength up to 170 kV/mm in a precision circular form provides reliable electrical isolation at defined, repeatable separations between conductors and high-voltage components.

✦ Laboratory Sample Vessel Covers

Used as non-contaminating cover elements in laboratory sample vessels, where PTFE Disc's chemical inertness and non-stick surface ensure that contact with samples does not introduce contamination or alter sample composition during preparation, storage, or analysis.

✦ Tribological & Electrical Insulation Research

Employed as stable substrates for tribological and electrical insulation studies in research environments, where dimensional precision and chemical inertness provide a controlled, reproducible test surface for characterising friction, wear, and dielectric behaviour under defined experimental conditions.
