Plastic water cups are a common type of water cup in our daily life. There are three main materials for plastic water cups. PC, pp and tritan are all high-temperature resistant plastic materials. But if you want to say which plastic cup is the most resistant to high temperature, then It must be a PC plastic cup.
In terms of temperature resistance, the temperature resistance of the PC plastic water cup can reach about 135°C, and the temperature resistance of different PC materials is also different, and some are even higher. Therefore, the PC water cup is the most resistant to high temperatures, but ironically, as the most resistant to high temperature plastic water cups, it is also the least resistant to high temperatures. Because PC material contains bisphenol A, bisphenol A will be released at high temperatures, and long-term intake of the released bisphenol A will cause cancer. Therefore, some people with knowledge of water cups will not use PC cups for serving. boiling water.
The second is the pp plastic water cup. The temperature resistance of pp material is generally around 120°C. The pp plastic material does not contain bisphenol A. Because of this, the pp material is the only plastic material that can be heated in a microwave oven. Plastic material. Then comes the tritan material. The temperature resistance is generally around 96°C. Although the temperature resistance of the Tritan material is the lowest among the three materials, the safety of the tritan plastic material is high.
