What are the characteristics of several commonly used materials for water bottles?

At present, the commonly used water cup materials are glass, ceramic, plastic and metal. Each material has its corresponding material characteristics. Only by mastering the correct usage method can the water cup be used healthily.

The glass material can be said to be the safest and healthiest material among the water cup materials. It does not add any chemical substances in the manufacturing process, and is smelted at high temperature, and it has high transparency and is easy to clean and is not easy to breed bacteria. But the disadvantage of the glass water cup is that it is fragile and has strong thermal conductivity. There is a danger of burns if used improperly.

Plastic water cups are also divided into many materials, such as pp material, PC material, etc.

Of course, the safest thing is still the tritan material. Tritan is a designated material for European and American infant products. It is healthy, non-toxic, and does not contain BPA. It is currently the safest plastic material. The only shortcoming is that the temperature resistance of the tritan material is low, the temperature cannot exceed 96 ℃, too high temperature will cause the cup to deform.

Metal cups are mostly stainless steel cups. The heavy metal substances contained in these materials are usually relatively stable. But it is not suitable for some other acid-alkaline beverages such as coffee, orange juice, etc. Because the heavy metal substances in the cup are easy to dissolve under the environment of strong acid and alkali, which is harmful to human health.
