Dapeng Huang, manager of product training department of lock lock, said that he had not touched other metal thermos cups, but he did not rule out the possibility of using other metal materials. However, at present, whether it is domestic independent brands or imported products, the mainstream material used in thermos cups is still stainless steel.

If it is an ultra-light stainless steel thermos cup, firstly, the thickness of the stainless steel cup wall material may be reduced, but this will lose some insulation effect. Second, it will reduce the weight by reducing the external plastic parts of the thermos cup, such as replacing the commonly used PP material with ABS plastic. It is understood that ABS plastic is light in weight and easy to process and manufacture, and is generally used as special-shaped accessories or small-sized accessories. However, ABS plastic has poor heat resistance and can withstand about 80-87℃.

Extended data:

There are two commonly used standards about the insulation effect of thermos cups: the standard of thermos cups and the standard of thermos cups. The mainstream view is that the time limit of thermos bottle is 12 hours, and the temperature of 12 hours is not lower than 48℃. There are also standards for single-layer cover thermos cups, with 6 hours as the insulation time limit, and 6 hours is not lower than 52℃.
