Wacker Elastosil® R 701/70 Silicone Rubber
Categories: Polymer; Thermoset; Silicone; Silicone Rubber

Material Notes: Product description: ELASTOSIL® R 701/70 is a non postcure HCR grade for extrusion and molding applications.

Special features:

  • heat- and reversion-stabilized
  • Non-post-cure properties: The differences in the mechanical properties of postcured and non-post-cured vulcanizates are only very slight. When Curing Agent E is used, blooming of the decomposition products will not occur.
  • The compounds may be blended to produce any shore hardness value between 40 and 80. Blends with products from other series are also possible.
  • good resistance to mineral oil
  • high elasticity and very low compression set, even when Curing Agent E is used
Application: The compounds are recommended for all kinds of seals that come into contact with mineral oils. ELASTOSIL® R 701/70 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 rolls.
