Hydrophobic Silica - compilant to FDA 21 CFR 177.2600
(OP)
Hello.
I found this helpfull forum during my www search.
I am a enigneer for rubber compounding in Germany.
I have to develop a white EPDM compound for food contact.
My problem is to find a silica filler, that is hydrphob, this means treated with silan by the producer,
or a single silane (to mix it together with untreated silica in our internal mixer)
that complies with FDA 21 CFR 177.2600.
This is because of the parts should have a low water swelling and good abrasion resistance.
Or are there any other opportunities.

thanks for the notes.
Does anybody know, if it is possible to use maleic anhydride in FDA 21 cfr 177.2600 conform compounds.
With this it is also possible to combine silica with the polymerchain.
There are some special EPDM grades availiable with maleic anhydride in it.
