What material is good for insulated cups

A good thermos should have the characteristics of long-term insulation, not easy to burn, and easy to clean, and the choice of material also has a great impact on the performance of the thermos.
At present, the main insulation cup materials on the market are as follows:
1. Stainless steel: Stainless steel insulated cups are a common type in the market, usually with a double-layer or three-layer stainless steel structure, which has good insulation performance, strong durability, and is not easily broken or deformed. Stainless steel insulated cups have a relatively thick material and good insulation effect, but their price is relatively high.
2. Glass: Glass insulated cups are also quite common, mainly using double-layer or three-layer glass structures, with the characteristics of good insulation performance and easy cleaning. The material of glass insulated cups is relatively thin, and the insulation effect is relatively poor, but the price is relatively affordable.
3. Ceramics: The materials used to make ceramic insulated cups are usually ceramics or porcelain, which have good insulation performance and exquisite appearance. However, ceramic insulated cups have a shorter insulation time, are fragile, and weigh more.
4. Plastic: Plastic insulated cups usually adopt a double-layer or three-layer structure, which has the characteristics of good insulation performance, lightweight and easy to carry, and the appearance is also relatively diverse. However, plastic insulated cups may have an odor and are not suitable for storing beverages for extended periods of time.
Taking all factors into consideration, double-layer or three-layer stainless steel insulated cups are a good choice, with excellent insulation performance, sturdy structure, easy cleaning and other advantages
