Rubber recipe ammonia 1

[Mating]

Hi all
I need help for a rubber recipe to resist anhydrous ammonia and to have low permeability.

I choose to use one of these three rubber : EPDM, IIR and CR.

Any Help for the rest of the recipe ? Filler, accelerators, plasticizer ...

Thank you

A peroxide cured EPDM would be an excellent choice.

Thanks Pete51 for your help.
is it better to use filler like CB or clay ?
you advise me to use a plasticizer or not?

Thanks

Like Pete on this one.

Peroxide Cure EPDM rubber. A plasticizer will make the recipe more flexible, not necessarily making it low permeable.
