Polytetrafluoroethylene (PTFE) Gasket

Core Features

• Ultimate Chemical Inertness: Resistant to almost all chemicals, including strong acids, alkalis, and solvents across the entire pH range of 0-14 (except for molten alkali metals and elemental fluorine).

• High Purity & FDA Compliance: Naturally non-toxic and "clean," making it ideal for applications requiring FDA-grade materials in food, beverage, and pharmaceutical industries.

• Wide Temperature Resilience: Maintains structural integrity and sealing performance in temperatures ranging from cryogenic to -200℃ up to 260℃

• Multiple Material Grades: Available in Virgin PTFE (for maximum purity), Expanded PTFE (ePTFE) (for superior compressibility and bolt-load retention), and Filled PTFE (with glass fiber, carbon, or bronze for enhanced mechanical strength).

Technical Advantages

• Low Coefficient of Friction: Features a non-stick surface that ensures easy removal during maintenance, preventing damage to flange faces.

• Zero Water Absorption: Completely hydrophobic, ensuring that the gasket material will not swell or degrade when exposed to moisture or liquid media.

• Excellent Dielectric Properties: Acts as an outstanding electrical insulator, suitable for specialized electronic and electrochemical sealing applications.

• Aging & Weathering Resistance: Highly resistant to UV radiation and atmospheric aging, ensuring a long service life in outdoor or harsh industrial environments.

It is widely used in industries including the chemical industry, petroleum, food and pharmaceutical, electronics, water supply, and drainage. It is applicable for static sealing of equipment like pipe flanges, valves, pumps, and reactors, especially suitable for sealing requirements of strong corrosive media, high-purity fluids (such as food and medicine), as well as high and low temperature working conditions.
