ELASTOSIL® R 805/75 OH
Vulcanisates made from ELASTOSIL® R 805/75 OH are noted for their good resistance to engine oils and aggressive mineral oils, even at high temperatures. They have good mechanical properties and a low compression set.
Eigenschaften
ELASTOSIL® R 805/75 OH is an oil resitant 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.

Datenblätter
ELASTOSIL® R 805/75 OH can be processed by compression, transfer and injection moulding. Usually post-curing is not necessary. To achieve an optimum compression set, it is advisable to post-cure the material for 4 hours at 200 °C.
ELASTOSIL® R 805/75 OH is especially recommended for the production of shaft seals.
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".
