Why is a silicone cup better than a stainless steel cup?

Silicone is widely used in our life. Food-grade silicone is internationally recognized as a safe, non-toxic, colorless and odorless material, which can protect the environment from pollution.Because after vulcanization silica gel has excellent high temperature, low temperature, weather resistance, hydrophobicity, electrical insulation, physiological inertness and other characteristics;Therefore, silica gel has been widely used in various countries, and it also appears in some important places. For example, in the military, the silicone coated hardware used in military metal components;Life, from small earplugs to large aircraft cockpit silicone seals and so on.

Stainless steel is a synthetic metal that contains chromium and nickel. Stainless steel is resistant to weak corrosive media such as air, steam, and water, but we all know that metals are harmful to the human body, especially chromium and nickel. Long-term contact with stainless steel will cause certain harm to the human body. This is just contact with stainless steel.

Why is silicone folding cup better than stainless steel cup?

1. Silicone is more stable than stainless steel. Stainless steel will react chemically when it comes into contact with acids and alkalis; it will produce substances harmful to the human body.  Especially when the stainless steel cup and traditional Chinese medicine are packed together, the ingredients in the stainless steel cup will react chemically with the alkaloids, organic acids and other components in the traditional Chinese medicine, which will easily make the medicine ineffective or generate more toxic chemical substances. On the contrary, the silicone folding cup does not have these problems. The silicone product is based on the silicon-oxygen (Si-O) bond as the main chain structure. The bond energy of the C-C bond is 82.6 kcal/mole. The Si-O bond The bond energy of silicone is 121 kcal/mole, so the thermal stability of silicone products is high, and the chemical bonds of the molecules will not break or decompose at high temperatures. Therefore, silicone is resistant to high temperatures and low temperatures, and can be used in a wide temperature range. Whether it is chemical properties or physical mechanical properties, the change with temperature is very small. Therefore, using silicone folding cups is much safer than stainless steel cups.

2. Because of the characteristics of silica gel, it can be made into very soft items, or it can be made into items with average hardness. And because stainless steel is an alloy, the metal is very hard; so the things it makes are basically hard. When you go out, carrying a stainless steel cup will take up too much space, while the silicone folding cup will not. When you don’t need to use it, you can fold it up and put it in your bag without taking up any space and lighter weight.

3. The silicone folding cup can be made in different colors, in line with people's different aesthetics, and the color will not affect the safety of silicone. For stainless steel, there is only one color and a single choice.
