- Application Details
- 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.
Processing
- 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.
