PVC heating will produce chlorine, so it is not environmentally friendly materials, PET and PP are environmentally friendly materials
PVC at room temperature is no problem, although there will be a small amount of chlorine release, but if the stabilizing agent and other additives, basically that is environmental protection, there are a lot of doors and windows, furniture, daily necessities are PVC material. But when the temperature is relatively high, will accelerate the decomposition of PVC, the release amount of chlorine will also increase, even add some stabilizers and other additives, to a certain extent, but limited, general PVC temperature exceeds 80 degrees will soften, more than 110 degrees, will become very unstable, accelerate the decomposition of 150-160, will so, all need to melt, high temperature heating will not use PVC, like the PVC hot water bag, formal are made by special technology, will be much more stable, the release of chlorine is very small, but also relatively soft, feel good.
