What are the advantages and disadvantages of PP and PC water bottles?

1. Both PC and PP can be used as food grade plastics. Many people say that only PP is food grade. This is a conceptual question. Food grade refers to relevant certifications, such as US FDA, other EU, Japan, etc. There are also certifications, but the FDA is the most widely applicable, so from this point of view, it cannot be proved that PP is healthier, and there are many products of both.

2. The harm of PC comes from BPA, which is bisphenol A. Everyone knows this question. The harm of bisphenol A is not as great as the legend. Completed animal experiments also prove that the harm is developmental, there is no need to alarmist, so pregnant women and adolescents should pay due attention. This happens because exposure to BPA is not an occasion. In addition, the doses in animal experiments are very large. The content of bisphenol A in PC plastics is still very good.

3. PP is not absolutely safe, and the source of suspected PP is much more harmful than the PC from regular channels. Many PP plastic products on the market are recycled materials. The hardest hit areas are straws and disposable products, and PP is in the production process. Catalysts are also used, usually containing titanium and aluminum.

4. PC has excellent performance and is an important engineering plastic. It has good temperature resistance and does not have the problem of not being able to hold hot water; PP has general performance, but hot water is no problem.

5. Ceramic and glass are safer than plastic. This is also based on reliable sources. Some china clays or enamels contain heavy metals, which can separate from the firing process. This article is not to say that plastic is good, but that any material is insufficient and cannot be generalized. The relationship between PC and PP is the same.
