Product Description

Product Overview

PTFE Precision Lathe Machining parts are custom-manufactured components made from polytetrafluoroethylene (PTFE), known for its exceptional chemical resistance, low friction, and wide operating temperature range. These parts are produced using high-precision lathe machining techniques, ensuring tight tolerances and smooth surface finishes. Ideal for applications requiring high purity, electrical insulation, and reliable sealing performance.


Key Features

  1. Excellent Chemical Resistance: Inert to almost all industrial chemicals and solvents

  2. Wide Temperature Tolerance: Operates reliably from -200ºC to +260ºC

  3. Low Friction Surface: Reduces wear and energy loss in moving parts

  4. Precision Machining: Maintains tight dimensional tolerances and clean edges

  5. Non-Adhesive & Anti-Stick: Prevents buildup of materials during operation

  6. Non-Toxic and FDA-Grade Options Available: Suitable for food and medical industries
