Is a Double-layer Cup Equal to a Thermos?

I believe that many thermos bottle manufacturers will find that many people have incorrect concepts and understanding of thermos when communicating with customers. They believe that as long as it is a double-layer cup, it can play a role in heat preservation. In fact, this statement is not entirely correct.

The reason why a thermos is called a thermos is because it has a heat preservation function. The principle is that the thermos uses tailless vacuum technology to evacuate the air in the middle layer of the double-layer stainless steel thermos, which can delay heat transfer and make the thermos have the function of heat dissipation.

Generally, stainless steel, ceramics and other materials can be used for the vacuum process, while double-layer plastic cups, outer plastic inner steel cups and outer steel inner plastic cups are not available. At present, the plastic thermos bottles on the market only have a heat preservation function, and their heat preservation function can only last for 2 to 3 hours at most. Their thermal insulation effect is far inferior to that of vacuum insulation. The lower the room temperature, the faster the cup loses heat. Although the double-layer plastic bottle can keep warm, it only lasts two to three hours.

Therefore, under the same double-layer condition, the heat preservation effect of stainless steel and ceramic thermos is stronger.

The double-layer stainless steel vacuum thermos produced by Dongguan Baifa Plastic Electronics Co., Ltd. insists on using food-grade 304 stainless steel or medical-grade 316 stainless steel in material. The heat preservation time can reach 18 hours, and the cold preservation time can last up to 24 hours. The entire production link adopts AQL2.0 inspection standards, which are far higher than peer standards. All links adopt a full inspection system to ensure that each product is a high-quality product.
