How long can a thermos keep hot and cold?

There are many kinds of cups, but the most special one is the thermos cup, because the thermos cup has a unique insulation function, and other types of cups do not. Consumers will pay more attention to the insulation time of the thermos when they buy the thermos. So how long can the thermos be kept warm?

Insulation cups are generally divided into ordinary insulation cups and vacuum insulation cups. The insulation time of the vacuum insulation cup is much longer than that of the ordinary insulation cup. The heat preservation time of an ordinary vacuum flask is generally about 2-3 hours, while the vacuum heat preservation cup can reach more than 12 hours. Moreover, if the insulation cup has been treated with special processes such as copper plating and tailless vacuum process, the holding time will be correspondingly longer.

The vacuum flask produced by Dongguan Zhanyi Commodity Technology Co., Ltd. is made of sufficient materials and exquisite workmanship. The material adheres to the combination of food-grade 304 stainless steel inside and outside, or a combination of 304 stainless steel outside and 316 stainless steel.
