Silica gel is a highly reactive adsorbent material and is an amorphous substance. Silicone is mainly composed of silica, which is chemically stable and non-combustible. Because silicone is non-toxic and tasteless, environmentally friendly and biodegradable, as well as high temperature resistant and many other characteristics, silicone products are now more and more popular in the market, but many consumers are always unable to distinguish which materials are food-grade silicone and which materials are ordinary silicone. Now we will introduce you how to distinguish them simply.
General silicone is used for processing industrial products, while food-grade silicone is used for processing products that are closely related to life, such as a series of silicone kitchenware.

● How to distinguish specifically between food-grade silicone and ordinary silicone:.
Pull by hand: this is a simple method to test when you see the product. Visual inspection is fine. How to operate: Hold the silicone product with your hand, focus on one place, and then pull hard to both sides. The one with white appearing is ordinary silicone, and the one without white appearing is food grade silicone.
Nose smell: if it is pulled up white and a pungent smell, then you can conclude that it is ordinary silicone, not food-grade.

● What are the differences between food-grade silicone and ordinary silicone.
Food grade silicone is vulcanized by platinum, high elasticity, high transparency and high tear strength. Ordinary silicone has a smell and is not transparent. Food-grade silicone is in line with ROHS and other environmental requirements, Bezit silicone products through the U.S. FDA and the EU LFGB food inspection product certification, there is no pungent smell, and can be in contact with food-related things, ordinary silicone can not, ordinary silicone and food-grade silicone is certainly not the same, food-grade silicone is to have FDA and other related certification, can be in direct contact with food. A lot of ordinary silicone is not food-grade certified.

The cost of ordinary rubber is low, the quality of the product is medium, and stretching will appear white phenomenon, tearing effect is general. The vapor phase rubber is improved on the basis of ordinary rubber, the raw material is more high-quality stretching without whitening phenomenon, better service life, the use of a wider range of fields, the density of raw materials of higher purity, the price is relatively expensive.
In general, there is no use of ordinary silica gel instead of food-grade silica gel to do the raw material, but we as consumers, more knowledge about silica gel is also very necessary, there will inevitably be some bad business.
