PTFE – Polytetrafluoroethylene

TFE, PTFE, FEP, PVDF, ETFE, ECTFE, PFA, PCTFE and other Fluoropolymers

Virgin PTFE Sheet and PTFE Rod

Virgin PTFE material is used frequently as a bearing or non-stick surface. It is an excellent choice for caustic fluid handling valves and fitting. Massive size range in extruded rod, molded rod, tubular bar and thin sheet, plate and film. PTFE is also known as: Fluon®, Diakin®, Flouroplastic®, Fluoropolymer®, Neoflon®, Polyfon®, Chemfluor®, and more. PTFE plate, sheets, rods, strip, slab, block and tubes are normal stock items. The entire range of Fluorocarbon materials are high heat and chemical resistant performance plastics.

Other Fluorocarbon Based Materials We Supply in Sheet, Plate and Round Rod: FEP – Fluorinated Ethylene Propylene; PVDF – Poly Vinylidene Difluoride (Kynar®, Tecaflon®, Sustatec® and more); ETFE – Polyethylenetetrafluoroethylene (Tefzel®); ECTFE – Ethylene Chlorotrifluoroethylene; PFA – Perfluoroalkoxy; PCTFE – Polychlorotrifluoroethylene (formerly KEL-F® or Neoflon®)

Why you should use PTFE (Fluoropolymers):

Very slippery and non-stick
Wear resistance
500 degrees F continuous use temperature
Excellent chemical resistance
Very easy to machine and fabricate
PTFE Rod available from .125″ – 6″ as standard
Larger sizes are molded per order
PTFE Sheet – Film from .005″ – 3″ thickness
PTFE Molded Tubing- Vast sizes are available – made to order
PTFE is ITAR compliant, and PTFE is RoHS compliant

Frequently used in:

Seals, gaskets and stem valves
Wear and slide machined parts
Chemical resistant fixtures
Pump parts and manifolds- from PTFE Rod
Scientific aircraft and electronic parts
Steam and high temp seals – from PTFE sheet
