Vulcanizates of ELASTOSIL® R 862/60 OH possess particularly good resistance to hot air in combination with several heat stabilizers. The vulcanizates are highly elastic and show extraordinary low compression set.


ELASTOSIL® R 862/60 is a heat resistant peroxide-curing silicone rubber.


The addition of heat stabilizers at service temperatures of more than 180 °C is recommended.


Further information to improve the heat stability by use of specific ELASTOSIL® AUX Heat Stabilizers can be obtained from the Technical Information Sheet "ELASTOSIL® AUX Stabilizers H" or from the latest brochures.

Specific features of ELASTOSIL® R 862/60 OH

  • Heat resistant
  • High rebound resilience
  • Ultra-low compression set

ELASTOSIL® R 862/60 OH is a peroxide curing high consistency silicone rubber suitable for the manufacture of molded articles like gaskets and bellows. Vulcanizates provide excellent heat stability by adding appropriate heat stabilizers, such as 1,5% ELASTOSIL® AUX Stabilizer H3 or 3% ELASTOSIL® AUX Stabilizer H1.

To obtain optimum compression set values it is advisable to post-cure articles made of ELASTOSIL® R 862/60 OH for 4 hours at 200°C.

The raw rubber requires the addition of peroxides for vulcanization at elevated temperatures. A homogeneous  incorporation is a must, but please avoid temperatures >30°C along the incorporation process in order to maintain best processing behavior. Pot life is depending on the used peroxide and storage condition.

For detailed information please refer to the latest edition of our brochure "SOLID AND LIQUID SILICONE RUBBER - MATERIAL AND PROCESSING GUIDELINES".
