Application Details
  • ELASTOSIL® R 510/70 S is crosslinked with 1.8 % crosslinker E [Bis(2.4-dichlorobenzoyl)peroxide, 50 %] at T > 135 °C or with 1.2 % Curing Agent C6 [2.5 Bis(t-butylperoxy)-2.5 dimethylhexane, 45 %] at T > 165 °C.
  • 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.
