How toxic is the plastic melting process. Do we need open air? Breathing mask?
@cindye good question!
Totally depends on the plastic type you’re working with. Some plastic types can produce harmful fumes, for example PET, PVC or PS. In general, if you stay within the temperature limits of PP, HDPE and LDPE, they are considered safe. However, since often over 50% of the mass of plastic are additives and you cannot tell which ones are in the plastic, it is better to be too careful than too little, because some additives can be toxic.
All plastic types produce toxic fumes when burned. (Obviousely)
I hope that helps,
all the best
