What Are the Common Used Materials of Thermal Cups

304 stainless steel

304 material is internationally recognized food-grade stainless steel with superior safety performance. This material has a density of 7.93 g/cm³ and can withstand high temperature up to 800°C. Due to its excellent resistance to corrosion, pitting, rust and wear, 304 stainless steel is the most commonly used material in the field of vacuum cups.

316 stainless steel

316 material is medical grade stainless steel, its corrosion resistance is better than the 304. And its high temperature resistance can reach 1200-1300°C. The insulated drinking cups made of this material will not experience thermal expansion or contraction. And even if it is accidentally filled with acidic drinks, it will not cause corrosion or heavy metal leakage. But its price is relatively high, so it is a high-end choice among insulated mugs due to 304 stainless steel.

201 stainless steel

Because it has poor corrosion resistance and may release harmful substances, it does not meet food safety regulations and has been eliminated. However, in order to reduce costs, some manufacturers will use 201 stainless steel for the outer layer of stainless steel cups. but at least 304 stainless steel for the inner layer. Please choose carefully when purchasing.

Titanium material

Pure titanium thermal mugs have significant advantages in safety, insulation effect, durability, portability, antibacterial effect, etc. Nowadays, it has become a popular choice.

Ceramics material

Ceramic insulated mugs are not common in the insulated cup industry, and their prices are relatively high. The advantage of this type is that it is completely harmless and does not release harmful metal substances like other materials. In addition, ceramic thermos cups are particularly suitable for making tea because of their slow heat transfer, strong heat retention, and good thermal and cold change properties.

How Does an Insulated Tumbler Work?

Double wall vacuum insulated

Its heat preservation principle is based on the following aspects:

Vacuum insulation layer. The insulated cup usually consists of two layers of cup wall, forming a vacuum layer in the middle. This effect of isolating heat transfer is achieved by vacuuming, because in a vacuum state, heat will not be transferred, thus ensuring that the water or beverage in the cup can be kept hot or cold for a long time.

Inner insulation layer. Its inner wall usually uses quartz fiber, which is a mixture of quartz fiber cloth and glass fiber, as the insulation material. This material contains air inside and has a good insulation effect.

Outer insulation layer. The outer layer of the thermos cup usually has a layer of insulation material, such as plastic, silicone or rubber. These materials have low thermal conductivity and can reduce the impact of the external environment on the temperature of the liquid in the cup.

Reflection layer. The outer wall of the insulated cups will be sprayed with metal powder or powder coating. These insulation materials can reflect solar heat energy and further reduce heat dissipation.

In terms of physical principles, the multi-layer structure of the thermal cups can prevent temperature loss and effectively preserve internal heat. Good sealing performance is also an important factor in ensuring the insulation effect. The better the seal, the harder it is to transfer heat, making the insulation effect better.

Do Insulated Cups Keep Drinks Cold?

Of course. The working principle of a thermos is to reduce heat exchange through a double-shell design and a vacuum insulation layer. Whether it is to keep heat or cold, the basic principle is the same. In order to make the thermos keep water colder, you can put the thermos in the refrigerator for a while and then put ice cubes in the cup. In this way, the cups can keep the temperature of cold water for a long time. We have special insulated cold cups on sale, check the styles and choose now.

Can I put coffee in an insulated tumbler?

Actually, an insulated tumbler is a container that holds liquids, not just water. You can put coffee, tea, or even carbonated drinks in it.

How often should I wash my insulated cup?

To prevent bacteria from growing and odors from being generated, you need to clean it at least once a day. When cleaning, you should thoroughly clean the inside, outside and cap of the cups, including the mouth, bottom and wall of the cup.

Why do insulated cups stop working?

‌The most common reasons are sealing problems and damage to the vacuum layer.

Poor sealing of the thermos cup will cause heat to dissipate through the top, affecting the insulation effect. The insulation principle of the thermos cup relies on the vacuum layer between the double-layer cup body. If the vacuum layer is damaged and air enters, the insulation effect will be greatly reduced.
