PP actually has a high heat tolerance and as such, does not seem to leach many of the chemicals other plastics do. In mild, 70-degree weather, the researchers measured safe levels of the chemical in the bottled water. By contrast, thermoset plastics can only be heated once (typically during the injection molding process). Effects of storage temperature and duration on release of antimony and bisphenol A from polyethylene terephthalate drinking water bottles of China. 0000000664 00000 n There is no average plastic cup, it depends on the material of your plastic cup. At extreme temperatures polymers will simply burn down very quickly - leaving no toxic materials around. The fridge? Prolonged storage and elevated temperature especially contributed to leaching of these chemicals. $\begingroup$ Nah, I can tell the difference between plastic and stale. We often get asked by our customers what our baby bottle nipples are made of. It can be expected that storage at high temperature may enhance contaminant release into water from PET bottles. 꾍VO One commonly recycled plastic, however, could be melted by hot water. 1.
