ELASTOSIL® R plus 4020/50 MH
ELASTOSIL® R plus 4020/50 MH is an addition-cure, one-component high consistency silicone rubber for the manufacture of molded articles. Cured articles are of high transparency and exhibit excellent tear resistance.
ELASTOSIL® R plus 4020/50 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. Further information about an improvement of the heat stability by use of specific ELASTOSIL® AUX Heat Stabilizers can be obtained from the Technical Information Sheet "ELASTOSIL® AUX Stabilizers H" or the latest edition of our brochures.
