Chemical and Thermal Resistance

TD7000 is engineered to withstand prolonged exposure to various insulating fluids, including:

  • Mineral oil
  • Natural ester oil


However, it is
not recommended for use with:

  • Silicone oil
  • SF₆ gas


The material exhibits minimal volume change when aged in mineral oil at elevated temperatures, indicating excellent oil resistance.

Environmental Compliance

TD7000 is manufactured in compliance with current environmental and safety regulations:

  • Asbestos-free
  • Free from heavy metals (Pb, Cd, Hg, Cr(VI))
  • Free from polycyclic aromatic hydrocarbons (PAHs)

Typical Applications

Amorim TD7000 is ideal for use in:

  • Transformer gaskets
  • RIP bushing seals
  • Oil conservator tank seals
  • Compression damping layers


Its high-temperature resilience makes it particularly suitable for equipment operating in environments with elevated temperatures.
