Як відрізнити справжність силіконової трубки?

Why do manufacturers all emphasize that the products are made of silica gel? How can we distinguish real silica gel products?

1. Regardless of the size of the brand, it must be certified by the relevant national department. Food-grade silica gel is an inorganic polymer colloid material formed by polycondensation of silicic acid. The main component is SiO2 nH2O, with a content of more than 98%. It is non-toxic and tasteless, and has stable chemical properties. , does not react with any acid-base salt.

At present, infant products on the market involve silica gel materials, which are divided into pharmaceutical grade silica gel and food grade silica gel. Among them, pharmaceutical grade silica gel has higher standards and must be certified by the State Food and Drug Administration.

Infant and toddler products on the market in my country generally follow three national standards: China, the United States, and Europe. No matter which country’s standard the product is implemented in, it can only be guaranteed to be genuine if it is certified by the State Food and Drug Administration. Be sure to see clearly when buying.

2. Latex and rubber are misleading, teach you three tricks to identify

Since the edible silica gel is refined and sterilized, it can be mixed with food and medicine according to the required amount to directly ensure that the food is dry and eaten together with the food, without any toxic and side effects on the human body. Therefore, parents who pay attention to the safety of baby entrances are inclined to baby products made of silicone materials.

At present, there are many baby products that use latex and rubber as silica gel. Even people in the industry have to distinguish carefully to distinguish the real from the fake. Professionals generally choose through the following three methods:

First: try elasticity: Rubber and latex have better elasticity, while silica gel is relatively fragile. When choosing, you can try the elasticity first. If the elasticity is good, it may be rubber;

Second: look at the color: rubber and latex cannot be made of transparent products due to the high content of impurities, while silica gel is colorless and transparent. To make transparent silicone rubber products must use silica gel raw materials

Third: smell: rubber and latex products have a strong smell, and they will smell pungent when you smell them. Some manufacturers add fragrance to cover up the smell, so it is much better to choose silicone materials.

Finally, because the production process of silica gel is relatively complicated, the price will not be particularly low. Therefore, when purchasing, don’t buy low-priced silica gel products for the sake of taking advantage of them.
