PTFE / Teflon
- Alternative Designations: Polytetrafluoroethylene
Description:
This is a highly slippery material with excellent resistance to extreme temperatures. It has outstanding insulating properties and is resistant to industrial chemicals. Due to its low coefficient of friction, it is widely used in the production of gears, bushings, slide plates, piston rings etc. Teflon’s density and stiffness gives it easy machinability. However, its high coefficient of expansion and stress creep make it difficult to obtain tight tolerances.

CNC machined part without surface finishes (3D render, aluminium)Bead blasting (3D render)
Bead blasting
Bead blasting involves spraying a pressurised stream of tiny beads of media, plastic or glass beads, from a nozzle onto the surface of the part. This removes the burrs and imperfections, leaving a smooth finish.
Notes:The recommended part size is 6-600 mm in both height and width. Smaller parts are hard to hold and tough to produce an even surface.
Final result:
- Uniform, matte or satin-like appearance
- Slightly grainy in the touch

Custom Finishing
If you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually takes 1-2 business days.
Notes:Submitting for manual review with a custom request does not guarantee a quote.
