Silicone products have the advantages of more environmental protection than plastic products, so it is more and more common in our daily life, and the application is also extremely extensive. However, silicone is divided into food-grade silicone and ordinary silicone, food-grade silicone is self-evident is used in food contact products, such as: maternal and child products, daily supplies, kitchenware, etc., and ordinary silicone is mainly used in machinery, electronics, automobiles and other industrial fields.

The difference between food grade silicone and ordinary silicone:

Food grade silica gel is an inorganic polymer silicone material made of silicic acid condensation, non-toxic and tasteless, stable performance, no harm to the human body;

Ordinary silica gel products to silicon oxide as a synthetic material, the synthesis process will produce byproducts of decomposition, if at high temperature, ordinary silica gel products are easy to volatilize harmful substances.

In terms of price, ordinary silicone is also much cheaper than food grade silicone.

In the face of two kinds of silicone raw materials that are similar in appearance and shape, how should we ordinary people distinguish food-grade silicone and ordinary silicone? The following Xiaobian will share two simple ways to distinguish:

1, ordinary silicone products in stretching will have whitening phenomenon, tear effect is obvious, and food grade silicone is not whitening (whitening) phenomenon;

2, this identification method is easier to understand, that is, smell with the nose, if it stretches up and becomes white at the same time as the pungent taste, it can be judged as ordinary silicone.
