ELASTOSIL® R plus 4846/30 MH

HTV silicone rubbers of the grade ELASTOSIL® R plus 4846/30 MH are oil-bleeding one-component platinum-curing compounds for the manufacture of molded articles. The vulcanizates form a thin oil film with lubricationg properties shortly after the curing process. As the crosslinking system is based on platinum cure no peroxide decomposition products can be formed during curing.


ELASTOSIL® R plus 4846/30 MH is a fast curing silicone rubber exhibiting excellent cut resistance. Thanks to addition cure, the vulcanization reaction is significantly faster compared to peroxide curing materials. No peroxide decomposition products are formed during vulcanization.


The addition of heat stabilizers at service temperatures of more than 180 °C 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.
