PTFE (polytetrafluoroethylene) static mixers are made of a translucent, chemically neutral, and non-toxic material with unsurpassed heat resistance and a smooth surface. PTFE, also known as Teflon, is widely used to coat cookware, especially non-stick pans. Static mixers with PTFE/FEP/PFA coatings are used in applications requiring high temperatures, resistance to corrosive chemicals, and long service life.
These stationary mixing systems are ideally suited for handling highly corrosive liquids. Both systems are suitable for low-pressure processes requiring high corrosion resistance and PTFE purity.
A stationary carbon steel mixer with a Teflon coating is a type of mixer with a polytetrafluoroethylene (PTFE) coating. PTFE is chemically inert to many reagents and therefore acts as a corrosion protection layer even at temperatures above 230 °C. Carbon steel pipes with a non-adherent PTFE coating exhibit good insulating properties. Carbon steel pipes with a PFA coating can be manufactured by extrusion, PFA injection, or vulcanization.
These stationary faucets are resistant to thermal shock and therefore do not deform even during sudden temperature changes. The materials and coatings used are employed in the manufacture of various components , including PFA-lined manifolds for pipework. All of these pipes are brittle and therefore do not require aging, as they are not susceptible to corrosion. The outer layer, the so-called PTFE coating, is chemically inert and does not change over time.
Here are some advantages of using PTFE stationary mixers in your stationary mixing systems:
- It is extremely corrosion-resistant.
Chemical resistance is ensured by a PTFE/PFA coating. The robust PTFE/PFA coating of the steel mixer guarantees the chemical resistance and structural strength of the piping system.
- Longer service life than conventional permanently installed steel fittings
Depending on the chemicals and materials flowing through stationary mixers, stationary mixing systems can last 3–4 years before corroding and becoming unusable. The necessary shutdown and replacement of a stationary mixing system results in downtime of several days. PTFE/PFA-lined pipes offer a longer service life, reduced downtime, and increased productivity.
- This ensures a smoother flow of chemicals.
Have you ever heard of Teflon pans? Teflon is the brand name for PTFE, a plastic used to coat cookware to prevent food from sticking. Thanks to its easy cleaning properties, Teflon is one of the most popular innovative materials for cookware. PTFE is also used in food processors that require a consistent flow of chemicals with minimal dust.
- Resistance to pressure and high temperatures
In addition to its non-stick and corrosion resistance properties, PTFE is suitable for high-pressure and high-temperature applications, which are widely used in our customers’ industries such as oil and gas, pharmaceuticals, EPC, personal care and food.
- High permeability
Prevents the penetration of corrosive substances and particles into the lining as well as the corrosion of the solid structure of the metal mixer.
