Don't know what the temperature is [should look in that new/old
copy of "materials Handbook"...] but PVC is Poly Vinyl Chloride
and when it's burned, it emits chlorine and maybe even 
Phosgene, nasty stuff.

The Chlorine, if combined with water, makes HydroChloric acid,
also not nice.

Telephone companies discover these things when they wire an exchange
with PVC insulated wire [used to be almost exclusively], have a fire
that the sprinklers try to attack, discover that the HCl released 
eats all the copper in the building.  Used to be real bad, what with
those old rotary switches...

Which explains why they went to Freon extinguishers....

And apart from all that, the molds have to be chrome plated, if not they
die REALY fast.
