Identify gasket material

[Davide Recchia]

I'd like to know the exact material of this gasket.
What's the best way to find out?

 

[3DDave]

Send it to an analytical lab?

Ask the supplier? You could ask for a safety data sheet.

I don't know of any reliable method to self-identity. Knowing what the gasket is exposed to can eliminate a lot of materials.

As Metten says, ask the supplier.

This is a custom part taken out from a commercial medical device, not from a supplier's catalogue.
It is very thin and stretchy, almost like a rubber latex glove but pretty sure it's not.
I was told it could be Santoprene (TPV), but not knowing that material I can't tell for sure.

Then do as 3DDave said - send it to an analytical laboratry for testing.

You could measure the density to rule out a few options.
I still think the supplier should be able to answer your question. They should know what they sell, certainly for a medical device.

I regularly get questions about the temperature range our products can be used at, which cleaning solvents may be used and in which media the seal or other rubber product should withstand.

You could find functional groups by FTIR Testing / SEM Testing

The gasket material was identified as Natural Rubber 45

Thanks for the update Davide. The 45 is probably the % of NR in the formulation, as it doesn't refer to any NR grade that I'm aware of.

Actually 45 is the shore A hardness
