Is there any way to preserve those synthetic materials and gain a longer shelf life (eg. 15+ years)? Eg. Heat sealed foil bags with excess air removed, or even filled with nitrogen? The idea is to buy several spare consumables when you first purchase the equipment, and break them out at regular intervals.

I have the same problem with vulcanized coatings that go sticky after several years (looking at you, 3D Connexion SpaceMouse, Saitek X52, etc).



You can remove the sticky vulcanised coating by rubbing will isopropanol or acetone. It's a bit of work, but beats throwing a working device out.


Yeah but then you're left with a hard plastic surface. Have you ever successfully re-coated?


No, I've just left it smooth. You can buy spray-on rubber paint that would probably work though.


If you manufacture something it's nice to ask what part breaks first and consider making it easy to replace.
