Properties
  • ELASTOSIL R plus 4020/60 MH is a fast curing silicone rubber exhibiting excellent tear resistance.
  • Thanks to addition cure, the vulcanization reaction is significantly faster compared to peroxide curing materials. No peroxide decomposition products are formed during vulcanization.
  • At service temperatures above approx. 180 °C the addition of heat stabilizers is recommended.
Note

Cure conditions: 15 min / 165 °C in press, post-cured 4 h / 200 °C for cured properties.
