1.For daily use, glass cups are definitely better than plastic cups. But also need to pay attention.
If you use a glass cup to make tea for boiling water, you need to choose high borosilicate glass. High borosilicate glass has high transparency and resistance to sudden cold and heat, even if it is poured into boiling water in winter, it will not burst.
Don’t choose a cup that is not very transparent and looks thick (like Laoganma, canned bottle). Although it looks thick, you will find it easy to "drop off" when you pour in boiling water. When it comes down, it will sometimes explode, which is very unsafe.
If it is a baby or a small pot for friends, parents must be worried that the glass is easy to break. At this time, you can choose a "plastic" cup.
"Plastic" is also divided into many materials,
2.Infants and children: PPSU material, high temperature resistance, parents can use water, steam, and microwave to sterilize it. Generally, baby bottles are made of this material. However, it is best not to sterilize the lid of the cup in this way, so as not to affect the tightness of the accessories.
3.There is also tritan material, which is also a very healthy material, but it cannot be sterilized at high temperature like PPSU material.
If you don’t have hot water for daily use, just install cold water with a PC. Hot water will release bad substances (bisphenol A)
If you need to install hot water for daily use, then choose PP material. It has good heat resistance and can be used in microwave ovens.
