- Application Details
The compounds are recommended for all kinds of seals that come into contact with mineral oils. ELASTOSIL® R 701/40 S is used especially when low compression set is crucial for achieving good seal properties. The compounds may also be used for making high quality silicone-rubber-covered rollers.
Processing
- ELASTOSIL® R 701/40 S is not recommended for the extrusion. ELASTOSIL® R 701/40 S can be vulcanized with peroxides normally used for press molding silicone rubber.
Properties
- Oil Resistance Properties
- Cured Properties
- Properties
- Good heat- and reversion-stabilized.
- Excellent resistance to mineral oil.
- Non-post-cure properties: The differences in the mechanical properties of post- cured and non-post-cured vulcanizates are only very slight.
- Note
Cure conditions: 0.7 % ELASTOSIL® AUX Crosslinker C1 (Dicumylperoxide), 15 min / 165 °C in press, post-cured 4 h / 200 °C
