Expanded PTFE joint sealant is produced by expanding 100% virgin PTFE into a highly fibrillated structure which exhibits characteristics significantly different than conventional PTFE. The expanded PTFE is much more flexible than regular PTFE and thus conforms easily to irregular and rough surfaces. In addition, the expanded material is easier to compress and exhibits excellent resistance to creep and cold flow.

Application:Expanded PTFE is soft and marshmallow-like, allowing it to readily conform to and seal flanges with irregular and damaged surfaces. Expanded PTFE is finding new applications in variety of industries including: Distillers; Petrochemical; Food and Beverage; Pharmaceutical; General Chemical; Power Generation; Marine, etc

PTFE Etched Sheet

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.

PTFE can be Etched on One Side (EOS)(Standard) or Two Sides (E2S)

PTFE Rods (Virgin Grade)

PTFE Rods & PTFE Sheets (Virgin Grade) exhibit high chemical resistance and ultra high-purity. Self-lubricating and with a low friction coefficient, PTFE (polytetrafluoroethylene) sheets and rods are ideally suited for the manufacture of high-temperature seals, insulators and bearings used in semiconductor, aerospace & chemical processing industries.

PTFE Rods, Sheets & Tubing exhibit the following characteristics:Lowest coefficient of friction of any known material.PTFE operates up to 250 Deg C.Tremendous chemical resistancePTFE is an excellent insulator.Limitations: low compressive & tensile strength.
