Why Choose PTFE

• Universal Chemical Resistance

  PTFE's carbon-fluorine bonds are among the strongest in chemistry — no common acid, base, solvent, or oxidizer attacks PTFE. The only exceptions are molten alkali metals (sodium, lithium), elemental fluorine, and a handful of exotic reagents. For chemical handling equipment in contact with aggressive process fluids, PTFE is the definitive answer.

• Lowest Friction of Any Solid Material

  PTFE has a static coefficient of friction of approximately 0.04 — lower than any other solid material. Bearings, slides, and seals in PTFE run with virtually no resistance without added lubricant. This property makes PTFE indispensable for dry-running seals, zero-contamination bearings, and medical/food applications where lubricant is prohibited.

• Widest Temperature Range

  PTFE operates continuously from -200°C (cryogenic) to +260°C — the widest temperature range of any common engineering plastic. For seals, gaskets, and components that experience thermal cycling or extreme operating temperatures, PTFE's stability across this range is unmatched.

• Non-Stick Surface

  PTFE's surface energy is so low that almost no material adheres to it — the basis for non-stick cookware, but equally important for process equipment where product buildup must be avoided. Chemical reactor linings, mixing bowls, and conveyor components are specified in PTFE to prevent material adhesion and contamination.

• Biocompatibility and Purity

  PTFE is non-toxic, non-leaching, and FDA 21 CFR compliant — used in food processing, pharmaceutical, and medical device applications. 

Common PTFE Grades

• PTFE

  100% pure PTFE — highest chemical resistance and electrical insulation. Standard for seals, gaskets, and chemical handling components where contamination must be avoided.

• Our Machining Capability

  PTFE is a regularly machined material in our facility — it is soft and ductile, requiring sharp tooling and light cutting passes to avoid surface smearing and dimensional inaccuracy. We use single-point carbide tooling with high rake angles and very light finishing passes on PTFE.  Tolerances held to ±0.05 mm standard. Virgin and filled grades are both stocked.

• Limitations & Cost Considerations

  PTFE has very poor creep resistance — it deforms permanently under sustained load (cold flow). This limits its use in high-load structural applications without filled grades that improve creep resistance. PTFE cannot be melt-processed or welded — it must be sintered from powder or machined from sintered billets. It is not bondable with standard adhesives — mechanical retention (flanges, grooves, press fits) is required. PTFE is also significantly more expensive than most engineering plastics — it should be specified when its specific properties (chemical resistance, temperature range, low friction) are genuinely required.
