Making Silicone Rubber metal detectable

[espresso51]

Anyone know how to make Hot cure Silicone Rubber metal detectable?
We want to mould some seals for a bakery and the parts need to be able to be detected by their metal detector in case they break up and land in the bread.

Mix powdered metal into the silicone.

Thanks, but I am concerned about it effecting the properties and I also need the mix to be FDA approved for food contact. Do you know of a metal powder that would meet this?

Try contacting detectamet, they can either supply the rubber already metal detectable or supply fda compliant additive
