Why do manufacturers all insist that their products are made of Special Material Braided Sleeve? How can you tell the difference between real Heat Shrinkable Braided Sleeve?

1. Regardless of the size of the brand, it must be certified by the relevant national departments.
Heat Shrinkable Braided Sleeve are inorganic polymer colloid materials made of silicic acid condensation. The main component is SiO2·nH2O, with a content of more than 98%. It is non-toxic, tasteless, and has stable chemical properties. It can remove caustic alkali and hydrofluoric acid under normal conditions. In addition, it does not react with any acid or alkali salt. Currently, infant products on the market involve Special Material Braided Sleeve materials, which are divided into pharmaceutical-grade Special Material Braided Sleeve and Heat Shrinkable Braided Sleeve. Among them, pharmaceutical-grade Special Material Braided Sleeve have higher standards and must be certified by the State Food and Drug Administration. Infant and child products on the market in my country generally follow three national standards: China, the United States, and South Korea. No matter what national standards a product complies with, it can only be guaranteed to be authentic if it is certified by the State Food and Drug Administration.

Professionals generally use the following three methods to choose:
First: Test the elasticity: Rubber and latex have better elasticity, while Special Material Braided Sleeve are more fragile. When selecting, you can try the elasticity first. If the elasticity is very good, it may be rubber;
Second: Look at the color: Rubber and latex cannot be made into transparent products due to their high impurity content, while Special Material Braided Sleeve are colorless and transparent. To make transparent silicone rubber products, Special Material Braided Sleeve raw materials must be used.
Third: Smell: Rubber and latex products have a strong smell, and you will smell a pungent smell when you smell it. Some manufacturers add fragrance to cover up the smell, so it is much better to choose Special Material Braided Sleeve materials.
Finally, the price of Special Material Braided Sleeve will not be particularly low due to the complicated production process. Therefore, when purchasing, do not think that you are taking advantage and buy low-priced Heat Shrinkable Braided Sleeve.
