Rubber desiccant?

Rubber desiccant?

(OP)
I know calcium oxide is very commonly used as a desiccant in rubber compounds, but I can't use CaO. Are there other desiccants that can be used?

Thanks,
tom

RE: Rubber desiccant?

Not that I know of Tom. Why can't you use CaO?

RE: Rubber desiccant?

(OP)
It adversely affects the curing of millable polyurethanes.

RE: Rubber desiccant?

Oh. Thanks for that Tom. I didn't know that.

RE: Rubber desiccant?

Have you checked with your supplier? They might be able to suggest an alternative.

RE: Rubber desiccant?

Have you tried MgO? Sometimes it can be used as desiccant because of his hygroscopic nature.
