- Plastics & Elastomers Processing Methods
- Application Details
- ELASTOSIL® R 805/75 OH can be processed by compression, transfer and injection molding. 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.
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.
