Are virgin PVC pellets toxic when melted in an injection molder?

Question

I keep seeing resources that the manufacturing of PVC plastic is toxic, but I can't find any info on virgin PVC pellets and if melting them in an injection molder is or isn't toxic.

Answer 1

No.  PVC manufacturing involves the toxic vinyl chloride gas.  However, PVC plastic should contain very little of the monomer, not enough to be hazardous.

Hazardous fumes will be released if the PVC starts to burn, so don't let the temperature get too high.
