Topic: Foam Safe for Mics?

[groovon]

Are there any precautions that need to be taken with any kind of foam in contact with mics or any other accessories?  I recently found the perfect-sized box in which to store my mics inside my gear bag and plan on cutting some foam to fit it, and then cutting out some slots to hold the mics (KM140s).  I have some nice foam that came inside some Western Digital hard drive boxes, but the drives were in their own antistatic baggies.  Is this foam likely to be fine to use, or is the foam used in Pelican cases, etc., a special foam suitable for electronics?

Once I had the screen printed AKG logo on a pair of C460s loosen and almost come off after an extended period wrapped in neoprene sheet (wetsuit material). I'd have thought it would've been OK, but watch out.
I've often wondered about the possible effect of the various plasticizers and other plastic/rubber chemicals on the diaphragm surface of expensive condenser mics. Anybody heard what  AKG, Neumann etc advise?
You can't be too careful with your mics.
Good luck

Also, I've heard (but not seen) that before the meltdown stage is reached, the foam can give off tiny particles of itself, which could settle on the membrane(s) of a microphone--particularly given that condenser microphones work on the same principle as electrostatic air cleaners.

I've got a pair of DPA windscreens that are 8.5 years old that shed black foam "dust" if I shake them.  A brand new pair does not

Here is a case I made by cutting anti-static high density plastic foam to hold a pair of BSC1's along with a second set of capsules. 

The box is an unused mic box from an old mic but the idea works with any appropriate sized box for your own needs.

Had posted it over in Team Busman but thought it fitting here too after seeing the OP on this thread.

... or at least wrap your anything in a plastic bag inside the case.

Birth control or mic storage?!?
