    • HVAC: Used in HVAC systems for duct sealing and insulation.
    • Electrical Insulation: Suitable for use as an insulator in electrical applications.
    • Marine: Used in marine environments due to its resistance to saltwater and weathering.
  2. Advantages:
    • Excellent Weather Resistance: Superior resistance to UV, ozone, and oxidation, making it ideal for outdoor applications.
    • Chemical Resistance: Good resistance to many chemicals, acids, and alkalis.
    • Thermal Stability: Maintains flexibility and resilience over a wide temperature range.
    • Water Resistance: Excellent resistance to water and steam.
    • Durability: Long-lasting performance in harsh environmental conditions.
  3. Limitations:
    • Oil and Solvent Resistance: Limited resistance to oils, solvents, and hydrocarbon fluids.
    • Abrasion Resistance: Not as high as some other rubber materials like natural rubber or nitrile rubber.
  4. Maintenance and Care:
    • Regularly inspect for signs of wear, cracking, or hardening, especially in harsh environmental conditions.
    • Clean with mild soap and water; avoid using harsh chemicals or solvents.
    • Store in a cool, dry place away from direct sunlight and ozone sources to extend the life of the rubber sheets.
