1. Expanded PTFE Material

• Primary Composition:
  • Made entirely of 100% expanded PTFE, which is chemically identical to regular PTFE but has a unique microstructure.
• Microstructure:
  • The expansion process creates a porous, flexible structure with multidirectional strength, enhancing compressibility and seal ability.
• Properties:
  • Chemically inert and resistant to almost all chemicals.
  • Wide temperature range (commonly -200C to +260C).
  • Non-aging, non-toxic, and biologically inert.

2. Optional Features or Coatings

• Surface Treatments:
  • Some gaskets have surface enhancements or coatings to improve adhesion or reduce friction during installation.
• Reinforcements:
  • For high-pressure applications, certain variants may incorporate a thin metallic core or other materials for added mechanical strength.

3. Design and Forms

• Flat Gaskets:
  • Cut from sheets or rolls of expanded PTFE for standard flange applications.
• Profiled Gaskets:
  • Shaped for custom sealing needs or non-standard flange types.
• Tape Gaskets:
  • Supplied as a continuous roll of ePTFE with an adhesive backing for on-site customization.

4. Certifications and Standards

• FDA Compliance:
  • Approved for food, pharmaceutical, and beverage industries.
• USP Class VI:
  • Suitable for medical and bioprocessing applications.
• TA-Luft and EN 13555:
  • Certified for sealing performance in industrial and environmental systems.

Applications

• Suitable for sealing uneven or damaged flange surfaces due to its excellent adaptability and compressibility.
• Commonly used in:
  • Chemical processing.
  • Food and beverage.
  • Pharmaceuticals.
  • Power generation.
  • Oil and gas.
