Now that I think more about it I have been working on a batch of g05s recently.  The anode cap and wire on all of them was covered in goo.  There's no styrofoam in there but I wonder what caused that insulation to soften so much.

I wouldn't dare venture to say Styrofoam is the cause of all roasted wires. But maybe something else? I'm at work right now and last night I got distracted with something else but.....

ANAICT PVC is known to outgas whatever is inside. Kind of makes me wonder exactly how safe PVC really is as a water pipe. ??? It's a property of PVC I guess. So, if an outgassed softener reacts with styrene maybe there's a "hardener" or solidifier that's put in some wire that's also outgassed?

It really makes me wonder if that was why these wheels suffered that way because some stabilizer was outgassed? They seem to be coated in a similar substance that makes up the electrical wire jackets.

Don't ask.  He's being petulant.   ::)

PVC = polyvinyl chloride

This is a common jacket type for wires in an industrial / commercial setting.  Where I work, we will use miles and miles of cable for a project.  We typically stay away from PVC jacketed cable.  One reason is it is not fire resistant.  When a fire is melting PVC jacketed cable, it lets off chlorine vapor, mixing with the sprinkler water, making acidic water spraying on everything.

This doesn't have much to do with polystyrene, but thought you might like to know a little more about PVC jacketed cable.

When we build a new school, I require Plenum rated (non-PVC) cable for all data/voice applications. PVC is nasty stuff.
