1,200 degree F - FDA - Wear Rail

[MuskieBoy]

Good Morning,

I have an FDA application. A heater element that reaches 1,600 deg f. located 4" above the a 303/304 Stainless Steel belt. I need a wear rail for the belt that won't melt. We are leaning toward a non-metalic component so we dont get micro-particles from metal on metal.

Any help would be greatly appreciated.
Thanks,
Dan

It would be handy to know what temperatures you would expect the part to attain.

We tried a test yesterday afternoon but blew the circuit after 5 min. We are trying again today.

I assumed 1,200 f as the elements are generating 1,500 to 1,600 f at 4" away.

No plastics will go near 1200F. You will need metal as it is in the red hot range. Even aluminium will not survive that temperature.

Looks like you will need a ceramic "wear rail", but it probably won't wear.

I was starting to look at ceramics last night. I have no experience with them. I know they will handle the heat but do not know if there are FDA rated ceramics. I'll investigate today.
Thanks for the help,
Dan

If they have ceramics rated to be used as medical implants, I see no reason why you can't find a suitable one for this. Sorry, but I cannot offer a suggestion...

Not even all ceramics will withstand those temperatures, take glass for instance.

Pat,

My comment was steered more towards MB's query about FDA-approved ceramics, though whether those approved ceramics also handle that high of a heat is beyond my knowledge base.

What about a basalt based product?

This example is resistant to heat lower than what you are looking for but it's a start....
