Just soft rubber. Nothing wrong with it actually, until you try to desolder the cap and pull a bit harder on the leads. So when pulling Panasonic caps for re-use, I always try to be more gentle.

I *think* that was a claim made by stj (but please excuse me if I got it wrong). Don't ask me what thread, though, because I can't remember even if my life depended on it.

Actually, speaking of this, I just noticed yesterday that I had some small Nichicon PM 5x11 mm caps leaking a little from both leads (green, puffy corrosion near the bung). So far, it only seems to be a bag of eight 16 V 100 uF caps only. I bought them back in 2010 or 2011 (or possibly early 2012) and used only a few, I think. Hopefully, this is just an isolated case with those caps and not a whole series problem. PM is supposed to be a replacement series for PL, so I wonder if they still have those quaternary ammonium salts problems. Meanwhile, it seems that my various bags of Nichicon PS caps (bought at same time as PM above) seem to be okay. PS is supposedly a replacement series for PR.
