2. PP material
PP is polypropylene with a high melting point of 167°C and is the only plastic that can be put in a microwave oven and can be reused after careful cleaning. The cup made of PP has good heat resistance and stable chemical properties. In addition to being corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents.
At present, bisphenol A is only found in PC material, but not in PP material. Of course, this is not to say how good PP plastic water cups are, because some relevant institutions have detected that PP plastic water cups will The release of bisphenol S at high temperatures is similar to that of bisphenol A, but as long as it is not used at high temperatures, there will be no problem.
3. Tritan material
