    PTFE O-Rings

    Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The best known brand name of PTFE is *Teflon® by DuPont Co. PTFE is a fluorocarbon solid, as it is a high-molecular-weight compound consisting wholly of carbon and fluorine. PTFE is an exceptional product but to use it properly you must understand what it is and what is not. PTFE is a very effective material that can be used in 99% of applications between -250 F and 450 F. Due to it's very low coefficient of friction, it can help to reduce energy consumption.

     

    In broad terms PTFE is a plastic. Like most plastics it has a very low recovery from compression, so it will not perform like an elastomer. This is important to consider if replacing an elastomeric o-ring with PTFE. In static applications switching to PTFE is not a major issue unless you have a highly thermodynamic application where recovery is required. In dynamic applications PTFE can be used. The details of the application including temperature, pressure, and speed must be considered.


    PTFE O-Rings Description:

    PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine. PTFE has one of the lowest coefficients of friction against any solid.

    PTFE has been used for many purposes, below are a few examples we have seen over the years of calling on Industrial companies over the years.

    PTFE O-Rings - Ideal for Food and Chemical applications

    PTFE Gaskets - And Gasket Materials have solved difficult applications in the sealing industry. Clean and resistant to high heat makes it suitable for food and semiconductor applications as well as Refining, Chemical and Power Generation.

    PTFE coatings - Allow any metal to be coated to extend the life of the part or protect it from attack. Coatings on Pump parts, Bearings, Machined Parts and Seals. PTFE added within seal materials such as graphite improve it’s sealing characteristics and allowing containment of Volatile Organic Chemical Compounds.

    PTFE Roofing - Was added to the list of applications due to UV resistance.

    PTFE coated Cloth - Adding weathering resistance to fabrics.

    PTFE Packings - Pumps and Valves need to be sealed. Containment of chemicals permit, companies to manufacture their product in a plant located close to populated areas. There are many various styles of PTFE based packings including EPTFE and FEP styles.

    PTFE Lubricants - From products like motor engine lubricants to grease, ptfe lubricants extend the life of equipment by greatly reducing frictional wear.

    PTFE Insulators - PTFE parts, cloth, gaskets and o-rings are use to insulate by greatly reducing electrical conductivity.

    Energy Sector PTFE uses
    Solar panel equipment can benefit from industrial PTFE coatings, using it for corrosion resistance on the frame, and as an insulator within the panels.

    Food Industry PTFE Applications that require clean non-hazardous release agents, means
    PTFE can be used in chocolate or other food molds. Of course we all know it’s great on pots and pans.

    PTFE in the Construction Trade means Tools and drill parts can be coated with PTFE to help them cut faster and resist wear and rust.

    PTFE Coatings in Personal Care Products including irons and curling irons.

    PTFE Coating Uses For Automakers and Car Part Manufacturing
    Carburetor parts, automotive plungers, bypass shafts and sleeves may be coated with PTFE

    Commercial and Retail PTFE Coating Services - Paints with PTFE to prevent “tagging” have been utilized. Building escalators have PTFE coated kick panels to prevent rusting shut.

    PTFE Coating Uses in the Safety and Security Market
    Door latches, lock parts and hinge pins can be coated with PTFE

    Appliances PTFE Coated Kitchenware
    ptfe coatings are applied to coffee maker parts, microwave dishes and ice cube trays

    Pet toys and dishes can be coated with PTFE to help to keep surfaces clean and safe for pets.
