Because plastic water cups on the market are made of various materials, including AS, PS, PC, ABS, LDPE, TRITAN, PP, PPSU, etc. Although these materials are all food grade, due to the characteristics of the material itself , some materials cannot withstand high temperatures and will deform significantly when exposed to high temperatures;
Some materials contain harmful substances that will not be released at low or normal temperatures, but will release bisphenol A at high temperatures. Currently, it is understood that the only materials that can be heated in a microwave oven without the above symptoms are PP and PPSU. If some friends have purchased the heated meal boxes given by microwave ovens, you can take a look at the bottom of the box. Most of them should be made of PP. PPSU is more used in infant products.

Most of the swollen draft beer cups that we use with rhombus-shaped raised surfaces are made of soda-lime glass. Such cups are resistant to heat and temperature differences. The performance is relatively poor, and the microwave oven will explode when heated. There is also a double-layer glass water cup.
