Expanded PTFE (ePTFE) is a superior polymer material derived from polytetrafluoroethylene (PTFE) through an expansion process. This material retains the excellent properties of PTFE, such as corrosion resistance, acid and alkali resistance, and non-stick qualities. Expanded PTFE Sheet also offers enhanced mechanical strength and thermal stability, making it widely applicable across various industries.

       Expanded PTFE Sheets Features:

  • Multidirectional Fiber Structure: The MultiTex expanded PTFE sheet is designed with a multidirectional fiber structure that provides exceptional stability both longitudinally and transversely. This design minimizes compression creep and elongation under extreme working conditions, ensuring the material’s long-term stability.
  • Wide Applicability: expanded PTFE sheets are suitable for all flanges, particularly those made of specialized materials such as fiberglass, enamel-coated surfaces, and ceramics. It is especially effective for sealing ceramic flanges and enamel-coated reactors.
  • Outstanding Sealing Performance: Even in cases where the flange sealing surfaces have been corroded, expanded PTFE sheets can still provide excellent sealing, ensuring the integrity and safety of the system.
  • Chemical Resistance and Non-Aging: Composed of 100% pure PTFE, expanded PTFE sheets possess superior chemical resistance and do not age easily. They have a low coefficient of friction and can be used in temperatures ranging from -180°C to +260°C without load.
  • Creep and Cold Flow Resistance: Special processing enhances the natural properties of PTFE, improving its resistance to creep and cold flow. This ensures safe and reliable use over a wide temperature range.
  • Ease of Processing: expanded PTFE is soft and easy to cut, making it suitable for both mechanical and manual cutting. This ease of installation makes it ideal for various industrial applications.
  • Environmental: The white, clean appearance of expanded PTFE sheets ensures they do not contaminate materials they come into contact with, making them ideal for environments with stringent cleanliness requirements.  expanded ptfe sheets semi-finished
