ELASTOSIL® AUX STABILIZER H1 is a ready-to-use additive comprising a heat stabilizing filler and a reactive silicone polymer which is a typical ingredient of ELASTOSIL® high-consistency rubber grades. This ensures that the batch is incorporated into the elastomer network during vulcanization and thus does not show any migration.


  • Thanks to its paste character, ELASTOSIL® AUX STABILIZER H1 can easily be incorporated into ELASTOSIL® R and R plus mixtures on two-roll mills.
  • No impairment of ELASTOSIL® R and R plus grades when dosage recommendations are observed.
  • Compatible with curing agents ELASTOSIL® AUX CURING AGENT C1, C6 and E as well as  ELASTOSIL® AUX BATCH PT 1 and PT 2.

Further information about an improvement of the heat stability by use of specific ELASTOSIL® AUX Heat Stabilizers can be obtained from the Technical Information Sheet "ELASTOSIL® AUX Stabilizers H" or the latest edition of our brochures.
