1. High quality insulated cup
These types of insulated cups usually use high-quality inner liner materials, such as 316 stainless steel, combined with advanced vacuum technology and good sealing design. After being filled with hot water at around 95 ℃, the water temperature can still remain above 50 ℃ -60 ℃ after 6-12 hours; After 24 hours, the water temperature can generally be maintained at around 30 ℃ -40 ℃. Many high-end series products from well-known brands even exceed this insulation level.
2. Medium quality insulated cup
These types of insulated cups mostly use 304 stainless steel inner liners, with relatively ordinary vacuum layers and sealing processes. After being filled with 95 ℃ hot water, the water temperature may drop to 60 ℃ -70 ℃ after about 6 hours. After 12 hours, the water temperature is about 40 ℃ -50 ℃, and after 24 hours, the water temperature usually drops to 20 ℃ -30 ℃. Some cost-effective brands of insulated cups commonly found in the market have insulation effects mostly in this range.
3. Ordinary insulated cup
The material and craftsmanship are relatively average, and the insulation performance is relatively weak. After injecting 95 ℃ hot water, the water temperature may drop to 70 ℃ -80 ℃ within 3-4 hours. After 6 hours, the water temperature may be around 50 ℃. After 12 hours, the water temperature often drops below 30 ℃. After 24 hours, the water temperature is basically close to room temperature.
