Pharmaceutical PVC will release toxic gases when heated?

That is the odor of some additives, mainly mercaptan organotin stabilizers, basically harmless to the human body. Pharmaceutical PVC to pass the health test, toxic additives can not be used. The harm to the human body is like the harm caused by atmospheric pollution, short-term nothing, long-term, large concentrations of harm. Our company originally did this, the workers and outsiders are generally not very good color, but there is no problem with the body. Once they left, after a few months, they looked great. We were exposed to much higher concentrations than your one. So the one you have just has an unaccustomed odor and is basically said to be harmless to the human body. But it's hard to say if you buy PVC pills from a manufacturer that doesn't have a registration certificate. Because some of the additives are toxic, no license manufacturers do not do testing, it is hard to say what is used inside.
