Benchmark stock rolls and sheets of raw and acid etched PTFE / Teflon in Canada.

Etched PTFE
PTFE is an amazing non-stick material, but what about when you need to glue it to the suface of another material ? In order to bond standard PTFE to another surface such as stainless steel, a process called “etching” is required. Typical applications would include the lining of chemical process tanks or other equipment used in caustic environments. When bonding is needed, sodium ammonia etching is usually the most economical answer. This process uses of a mixture of sodium and ammonia that is formulated to create a bondable surface both quickly and efficiently. Sodium/ammonia etching service complies with all applicable commercial, military & federal specifications for the surface treatment of all fluoropolymers including: PTFE, PFA, FEP, ETFE, PCTFE, PVDF, PVF, & ECTFE.
From microchips to full size rolls, fluoropolymers of any shape or complexity, including tape, sheet, tubing, molded shapes & machined parts of any configuration can be etched & bonded. This treatment can be accomplished on one or more surfaces, or selectively within close tolerances.

  • Note: Etched surfaces will discolor to a brown appearance.
  • May be Etched on One Side (EOS)(Standard) or Two Sides (E2S)

Chemical-Resistant Slippery Sheets and Bars Made from Teflon® PTFE

Made with Teflon® PTFE resins, these sheets and bars surpass most plastics when it comes to chemical resistance and performance in extreme temperatures. In addition to resisting most solvents, they are excellent electrical insulators. They’re easy to machine and have a naturally slippery surface that makes them a good choice for bearings, gears, and parts that slide and roll.

Sheets and bars with an etched texture have one side that is scuffed to readily accept adhesive; the other side is smooth and is made of FDA listed material.

Skived sheets and bars are more likely to curl than molded sheets and bars.

Benchmark stocks and converts PTFE Sheets in a wide range of thicknesses up to 1″.  Our thick gauge PTFE Sheets have excellent thermal and electrical insulation properties and a low coefficient of friction. PTFE is inherently super slippery and extremely temperature/chemical resistant, making it a highly suitable material to be used in the toughest applications. Benchmarks custom converting capabilities enable us to produce cut strips, rectangles, or custom die cut parts.

Thick gauge PTFE Bar, Rod, and Rectangles, also available.
