Rubber magnet curie point question
Rubber magnet curie point question
(OP)
Hello
I am developing a product which uses rubber magnets. The product will occasionally be subject to boiling water for short periods of time, as will be in a kitchen environment, frequently in the sink, when vegetables etc have their boiling cooking water poured away.
Are there rubber magnets on the market that are not affected by this for both the structure of the rubber and magnetic Curie point?
To be honest I have spoken to a number of manufacturers and I am getting mixed responses. I am unsure if this is because some are ill informed or perhaps are trying to persuade me to develop in the direction which fits their supply chain.
Any help would be very much appreciated.
Kind regards
Matt

RE: Rubber magnet curie point question
What you will probably have to worry about is the water affecting the rubber binder. There are so many different formulations, most magnet providers probably don't want to issue a blanket statement saying the binder can survive long term exposure to boiling water.
My suggestion is to buy some samples from a reputable supplier and test them yourself. If you can run a continuous stream of boiling water on the samples for a couple of hours, you can be reasonably certain they'll survive most normal kitchen environments.

Mike is right, the magnet is not the issue, the binder is. Put them in your rice steamer and cook them overnight. If they are crumbling move on to another source. Many rubber resins have decent water resistance.
