Properties

  • Good heat- and reversion-stabilised
  • Excellent resistance to mineral oil
  • Non-post-cure properties:
    The differences in the mechanical properties of post- cured and non-post-cured vulcanizates are only very slight. 

Specific features of ELASTOSIL® R 701/40 S

  • Oil resistant
  • Ultra-low compression set

The compounds are recommended for all kinds of seals that come into contact with mineral oils.
ELASTOSIL® R 701/40 S is used especially when low compression set is crucial for achieving good seal properties. The compounds may also be used for making high quality silicone-rubber-covered rollers.

The raw rubber requires the addition of peroxides for vulcanization at elevated temperatures. A homogeneous incorporation is a must to maintain best processing behavior. Pot life is depending on the used peroxide and storage condition. Please consider the technical data sheet of the corresponding curing agent.
