ptfe PTFE gaskets PTFE & PTFE-based gaskets

PTFE-based gaskets are sealing materials made from polytetrafluoroethylene (PTFE), a synthetic fluoropolymer of tetrafluoroethylene. PTFE is known for its excellent chemical resistance, low friction properties, and high temperature resistance.

PTFE-based gaskets are widely used in various industries due to their exceptional sealing capabilities. They are commonly used in applications involving aggressive chemicals, high-pressure systems, and extreme temperatures. These gaskets can withstand a broad range of chemicals, including acids, bases, solvents, and corrosive substances.

One of the key advantages of PTFE-based gaskets is their ability to maintain a tight seal even in demanding conditions. They have excellent resistance to compression set, meaning they can maintain their shape and sealing properties over a long period of time. This makes them ideal for applications where reliability and longevity are crucial.

PTFE-based gaskets also have low friction properties, which can help reduce torque requirements during installation and minimize wear on mating surfaces. They are often used in applications where preventing leakage and minimizing friction are critical, such as in pumps, valves, and flanges.

Another notable feature of PTFE-based gaskets is their ability to withstand high temperatures. They can operate in temperatures ranging from cryogenic levels up to 260°C (500°F) without losing their sealing properties. This makes them suitable for applications in industries such as chemical processing, oil and gas, pharmaceuticals, and food processing.

In summary, PTFE-based gaskets offer exceptional chemical resistance, low friction, and high temperature resistance. They are reliable sealing materials that can withstand demanding conditions, making them a popular choice in various industries.
