PTFE Polytetrafluoroethylene Seals

PTFE (Polytetrafluoroethylene) Seals for High-Temperature Applications

PTFE seals are used in high-temperature applications due to their high heat resistance and chemical inertness. PTFE is a synthetic fluoropolymer of tetrafluoroethylene and is known for its non-stick properties, high temperature resistance, and low coefficient of friction. PTFE seals are commonly used in a wide range of applications, including aerospace, chemical processing, and industrial manufacturing.

Fillers for PTFE Seals

To enhance the toughness and flexibility of PTFE seals, short glass fiber, bronze flashes, carbon, graphite, or a combination of these fillers are added. The fillers help to retain the shape and memory of the PTFE seal and improve its performance under varying temperatures and pressures. The choice of filler depends on the specific application requirements, and our team of experts can help you select the right filler for your application.

Energizers for PTFE Seals

To ensure a proper fit and seal, an energizer is often used with PTFE seals. Energizers are used to compress the PTFE seal and create a tight seal against the mating surface. The energizer can be made from various materials, including stainless steel, nickel alloys, and other metals. Our team can help you choose the right energizer based on your application requirements.

Benefits of PTFE Seals

PTFE seals offer several benefits over other sealing materials. These include:

High heat resistance: PTFE seals can withstand temperatures up to 500°F (260°C).
Chemical resistance: PTFE is highly resistant to a wide range of chemicals, making it suitable for use in harsh environments.
Low friction: PTFE has the lowest known coefficient of friction of any solid material, which helps to reduce wear and tear on the seal.
Non-adhesive: PTFE is non-adhesive, which means that it does not stick to other surfaces, reducing the risk of galling or seizing.

At NNK, we offer a wide range of PTFE seals designed to meet the needs of various high-temperature applications. Our team of experts can work with you to develop a custom sealing solution that meets your specific requirements. Contact us today to learn more about our PTFE sealing solutions.
