Is it harmful to contain boiling water in a plastic cup made of PC material?
The cup with the number 7 on the bottom is made of polycarbonate, PC. The general PC plastic cup can withstand -30-140 degrees Celsius, but this is the physical property of the material, it can only be said that the material will not crack and melt when used at this temperature.
However, from a food safety point of view, we will find that the higher the temperature, the more BPA is released from PC, and the faster the release rate. Therefore, the reason why PC poses a health threat is that it releases BPA at high temperatures.
So why does BPA make people "distracted"? BPA is a material commonly used in industry to synthesize PC and epoxy resin. It is ubiquitous in modern industry, from mineral water bottles and medical equipment to food packaging. The world produces nearly 27 million tons of BPA-containing plastics every year. Although it has great industrial uses, it is also harmful to humans. According to research, BPA can cause endocrine disorders and may even cause obesity caused by cancer and metabolic disorders. The EU believes that baby bottles containing BPA can cause precocious puberty. Starting from March 2, 2011, the production of BPA (a chemical substance) baby bottles will be banned. Therefore, if conditions permit, it is best not to use a PC cup to hold hot water, let alone heat it in a microwave oven.
Therefore, if you are choosing a plastic water cup and want to use it for boiling water, it is recommended to use PP and TRITAN plastic water cups, because of their low density, good thermal stability and insulation, and harmless to the human body.
