Description

  1. Applications:
    • Sealing and Gaskets: Used in seals and gaskets due to its excellent sealing properties.
    • Padding and Cushioning: Ideal for use in pads, strips, and cushioning applications.
    • Abrasion Resistance: Suitable for applications where wear resistance is essential.
    • Shock Absorption: Used in applications requiring high resilience and shock absorption, such as anti-vibration mounts and mats.
    • Weather Resistance: Suitable for outdoor applications due to its good resistance to weather and environmental conditions.
  2. Advantages:
    • High Elasticity: Natural rubber offers excellent elasticity, making it ideal for dynamic applications.
    • Excellent Abrasion Resistance: Good wear resistance, suitable for applications where durability is critical.
    • Good Flexibility at Low Temperatures: Maintains flexibility and resilience in cold environments.
    • Resistance to Impact: Effective in absorbing shocks and impacts.
  3. Limitations:
    • Chemical Resistance: Limited resistance to oils, solvents, and hydrocarbons.
    • Aging: Can degrade over time when exposed to sunlight (UV), ozone, and high temperatures.
    • Flammability: Natural rubber is flammable and should be used with caution in high-temperature environments.
  4. Maintenance and Care:
    • Regularly inspect for signs of wear, cracking, or hardening, especially in harsh environmental conditions.
    • Avoid prolonged exposure to direct sunlight and ozone-rich environments to extend the life of the rubber sheets.
