Genny,

There is a big difference between PVC and Teflon insulation.

PVC is cheaper (sorry, less expensive), melts at a lower temperature (like when you're soldering), has a lower voltage rating and is easy to strip.

Teflon is more expensive, has a high temperature rating, is chemical resistant, has a high voltage rating and is abrasion resistant and can be harder to strip.

Those were general differences.  With the actual manufacturer's numbers this could be worked into more specific details, pro and con.

Subject: [TN] wire coatings


Do you remember my question regarding the midplane assembly?
Turns out that there was a reel of mislabelled wire in house, and a whole
bunch of assembly has been done using a PVC coated wire, instead of the
teflon coated wire I spec'd.  Apparently the wire in question is obsolete,
but they like using it better than the teflon, and want to continue to use
that.
I don't know much about wire coatings - what is the difference between these
two coating types, and when would you want to or not want to use them.  I
need to decide whether we need to force them to change out the wiring
they've already done.
Sigh...
Thanks for your help in advance.
