- ELASTOSIL R plus 4020/40 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.
