ELASTOSIL® R Plus 4000/40 MH
- Chemical Family
- Silicones
ELASTOSIL® R Plus 4000/40 MH is an addition-cure, two-component high consistency silicone rubber used for manufacturing molded articles. The cured articles are known for their high transparency and excellent tear resistance. This fast curing silicone rubber exhibits high elongation values and exceptional tear resistance. Thanks to the addition cure process, the vulcanization reaction occurs much faster compared to peroxide curing materials. Importantly, no peroxide decomposition products are formed during vulcanization.

- Properties
ELASTOSIL® R plus 4000/40 MH is a fast curing silicone rubber exhibiting high elongation values and 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.. In order to obtain an intermediate hardness ELASTOSIL® R plus 4000/40 MH can be blended in any ratio with other grades of the ELASTOSIL® R plus 4000 series. In that case, the platinum catalyst batch ELASTOSIL® AUX Batch PT 2 should be added as the last component. At service temperatures above approx. 180 °C the addition of heat stabilizers is recommended.
