PTFE CHARACTERISTICS & BENEFITS

The extraordinary characteristics of PTFE make it the ideal choice in a wide range of products and applications. PTFE has a coefficient of friction that is one of the lowest of any material. PTFE is extremely abrasion resistant, making it adaptable to the harshest environments. In addition, PTFE can withstand a wide range of temperatures, from 260 Degrees Centigrade down to -270 Degrees Centigrade, and can even handle brief exposures at higher temperatures. PTFE also has excellent flame resistance due to its extremely high melting point, along with a very low rate of smoke generation and heat release. Another advantage of PTFE is that it is chemically inert and pure, and has no additional stabilizers, lubricants or plasticizers that would taint process fluids.

PTFE products have an extremely long service life, primarily due to PTFE retaining its original properties over a long period of time, even at extreme temperatures, in ultraviolet (UV) light, and when exposed to oils, oxidizing agents and solvents. PTFE also is extremely corrosion resistant, especially to acids, and harsh inorganic and organic chemicals. Additionally, the original properties PTFE remain the same even after extended time periods in water. Furthermore, PTFE is resistant to atmospheric aging in the form of discoloration, oxidation, and, as previously noted, is not affected by ultraviolet light

APPLICATIONS

The uses and applications of PTFE have grown enormously over the past 68 years. Probably one of the most famous uses for PTFE is as a non-stick coating found on cookware .However, PTFE is used in the semiconductor, medical, chemical, automotive, electrical, aerospace, filtration, wire & cable as well as petrochemical industries.

    * Chemical processing and petrochemical sectors: used for vessel linings, seals, spacers, gaskets, well-drilling parts and washers, since PTFE is chemically inert and resistant to corrosion
    * Laboratory applications: Tubing, piping, containers and vessels due to resistance to chemicals and the absence of contaminants attaching to the surface of PTFE products
    * Electrical industry: used as an insulator in the form of spacers, tubing and the like
    * Virgin PTFE had been approved by the FDA for use in the pharmaceutical, beverage, food and cosmetics industries in the form of conveyor components, slides, guide rails, along with other parts used in ovens and other heated systems.
    * Semiconductor sector: used as an insulator in the production of discrete components such as capacitors and in the chip manufacturing process.

In many instances PTFE in it purest form is a perfect solution. However, when an application demands a modification to the basic PTFE chemistry, Plastomer Technologies can help satisfy a broader range of physical, thermal, or practical demands. Examples include glass or bronze fillers for added stiffness and strength, carbon fillers for conductivity, and moly blends for added lubricity.
