- Why need copper lining for stainless steel vacuum insulated bottle tumbler?
An interior copper liner that reduces surface heat loss, to insulate hot liquids for 12 hours and cold for 24 hours or more.
Based on the tests data, with test environment 24+/-2℃，initial 95℃ hot water, we compared the water temperature at the test timing at 1Hour, 2Hour, 4Hour, 6Hour, 8Hour, 12Hour, 24Hour, it’s easy to see the difference between a stainless vacuum insulated bottle with Copper lining & without Copper lining, the average difference is about 15%.
2. Why copper lining shield can affect the vacuum insulation of a thermos bottle to have better heat preservation performance?
As you can see the picture above, the hot/cold drinkiing water stays hot or cold inside the vacuum insulated bottle, becuase the thermos vacuum insulated bottle creates an airless space between two walls which virtually eliminating the convection process and temperature change, and the copper liner can help eiminate the convection process inside the thermos bottle
