A bottle that can stand on a leaf, have you seen it?
Advantages of Space Cup
Lightweight. Much lighter than thermal water bottles or military water bottles, and even lighter than SIGG/LAKEN aviation aluminum water bottles of the same specification.
Durable. You may think that the transparent space cup looks weak, but in fact, today's space cups, whether they are the best NALGENE or a domestic brand that costs a few dollars in the supermarket, are all made of food-grade PC plastic without exception. Excellent electrical insulation, elongation, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance; also has the advantages of self-extinguishing, flame retardant, non-toxic, colorable and so on.
Heat conduction. It's hard to imagine how to hold your single-layer metal kettle when it's full of boiling water without a cover, and it's cool enough to handle in colder conditions. The disadvantage of low thermal conductivity of PC plastic is an advantage here. Although the thermal insulation cannot be compared with that of a double-layer thermal kettle, it is enough to ensure the comfort of hand-held in various environments.
How to choose a space cup
For the newly bought space cup, don't fill it with water immediately, you should wash it with water and soak it for 2 hours or soak it in vinegar for 2 hours, and don't pour boiling water directly when using it. Because many space cups or plastic products use "PC" material, and bisphenol A is the main synthetic raw material of "PC" material, special attention should be paid when using it for the first time. For this reason, it is recommended that when purchasing a space cup, you should first look at the packaging instructions. After reading the instructions, open the cup and smell it. If there is an odor, it means that the material of the cup is not up to standard, and there is a problem; the last thing to pay attention to is to touch it with your hands. When you touch the cup, it is best not to buy it if it feels bad and easy to deform or has uneven color blocks.
