1. It is not easy to draw a conclusion whether drinking hot water in plastic cups is harmful. Plastic cups are also divided into cold water cups and heat-resistant cups. Drinking hot water in a heat-resistant cup is generally harmless. If you drink hot water with a cold water cup for a long time, it may have a certain impact on human health.
2. Plastic is a polymer chemical material. When hot water or boiled water is filled in plastic cups, polymers are easy to precipitate and dissolve in water, which is harmful to human health after drinking. Moreover, there are many pores in the internal microstructure of plastic, in which dirt is hidden, which will also have adverse effects on human body if mixed with hot water.
3. We can judge whether the plastic cup can become hot water by observing the number of the bottom or body of the plastic cup.
4. "01"-PET (polyethylene terephthalate) is commonly found in mineral water bottles and beverage bottles. This material is heat-resistant to 70℃ and can be filled with normal temperature water in a short time, but it can't be filled with acid-base drinks or high-temperature liquids, and it is not suitable for exposure, otherwise it will produce toxic substances harmful to human body.
5, "05"-PP (polypropylene), PP plastic water cup is made of polypropylene, which has good thermal stability and insulation, can withstand the high temperature of 130℃, and is safe and reliable.
6. "06"-PS (polystyrene), the plastic cup made of PS is particularly brittle and resistant to low temperature, and cannot be used in high temperature, strong acid and strong alkali environments.
7. "07"-PC (polycarbonate) and other types, used for kettles, cups, milk bottles, etc. High safety, fall resistance, but not high temperature resistance.
