The ProGear stainless steel water bottle is double walled 18/8 grade stainless steel with vacuum insulation. The double wall is plated with copper for ultimate conductivity to keep drinks hot for 12 hours and cold for 48 hours. Holds 17oz of your favorite beverage
This bottle is both eco-friendly and practical. Thanks to the copper insulation, this vacuum bottle keeps drinks hot for 12 hours and cold for 48 hours, so you never have to worry about your drink quality on the go.
100% Safe, the copper is plated between the outer wall and inner wall. It is not on the side that touches the water or beverage, and never comes in contact with any liquid inside the container. The copper is NOT exposed to the outside elements as well.
Thermal Insulation Effect of Copper Plating on the Inner Wall
Under normal circumstances, the heat transmission path of the insulated water bottle has radiation, convection and transmission. The inner wall with the copper-plated layer reflects heat radiation, effectively reducing the heat lost due to heat radiation. The copper plating on the inner wall thus forms a heat-insulating layer in the vacuum insulated water bottle.
The vacuum insulated stainless steel water bottle with copper plating on the inner wall has a thermal insulated effect of about 30% better than that of the ordinary same type vacuum insulated stainless steel water bottle.
The copper plating performance of the liner is stable and the corrosion resistance is strong. The thermal radiation on the inner wall will be reflected back by the copper plating layer, which effectively reduces the loss of heat and greatly enhances the effect of heat insulation and cold preservation.
Sip in style with a top-quality water bottle.
