1. What is the material of the thermos cup?
1, cover
The lid of a thermos cup is usually made of plastic. But there are many kinds of plastics. Each plastic container has a triangle symbol (usually at the bottom of the plastic container), and there are 1-7 numbers in the triangle. Each number represents their manufacturing materials, namely 1 PET, 2 HDPE, 3 PVC, 4 LDPE, 6 PS. Among them, No.5 PP (polypropylene) is the safest plastic material and the only plastic that can be heated by microwave oven. Therefore, when choosing a thermos cup, the lid of the thermos cup is best made of PP.
2. Cup body
The cup body of the thermos cup is generally made of stainless steel, and the commonly used stainless steels are 304 stainless steel and 3 16 stainless steel. 304 stainless steel is internationally recognized as food grade (processed and filled) stainless steel. 18/8 means that this stainless steel material contains 18% chromium and 8% nickel. Materials meeting this standard have excellent corrosion resistance and good machinability. It is an absolutely safe and hygienic material, and it is the most widely used and safest raw material for high-quality thermos cups. 3 16 stainless steel (18/ 10): medical grade stainless steel! Its corrosion resistance, easy processing and welding performance are better than 304, but its cost is very high and it is rarely used.
