PTFE (Teflon)
Extreme temperature and chemical resistant plastic in sheets, rods & tubes for seals, gaskets, and bearings.
-260 to +260°C
Temp range
Inert
Chemical proof
Non-stick
Lowest friction
PTFE (Polytetrafluoroethylene), commonly known as Teflon, is an extreme-performance engineering plastic offering the widest operating temperature range and best chemical resistance of any thermoplastic. P&M Plastics machines PTFE components for seals, gaskets, bearings, insulators, and chemical-resistant applications.
PTFE's non-stick surface, ultra-low friction, and chemical inertness make it essential for demanding chemical processing, pharmaceutical, and food processing environments.
Key Properties
Common Applications
How We Fabricate PTFE
PTFE is machined using CNC routing and turning. It cannot be welded or solvent-bonded. PTFE has a tendency to creep under sustained load, so we advise on design considerations for high-load applications.

Frequently Asked Questions
What chemicals can PTFE resist? +
PTFE is virtually inert to all chemicals except molten alkali metals and fluorine gas at high temperatures. It's the most chemically resistant plastic available.
Does PTFE creep? +
Yes, PTFE has a tendency to deform (creep) under sustained load. We design components with appropriate wall thicknesses and support structures to manage this.
Can PTFE be welded? +
No, PTFE cannot be welded or solvent-bonded. Assemblies use mechanical fastening or compression fitting.
