- Application Details
- ELASTOSIL® R 752/70 OH is particularly suitable for the manufacturing of low-modulus rubber articles by compression, transfer or injection molding.
- Some special applications, such as highly damping elements, require silicone rubbers with low rebound resilience.
Processing
The raw rubber requires the addition of peroxides for vulcanization at elevated temperatures. A homogeneous incorporation is a must. At processing temperatures below 30°C the stickiness on the roll mill can be reduced. Pot life is depending on the used peroxide and storage condition.
