People's living standards are constantly improving, the use of silica gel products in our daily life is becoming more and more common, compared with plastic products, silica gel products more environmentally friendly, in line with the current people's concept of green, environmental and healthy life, and in fact, many materials in life are replaced by silica gel products.

Do you still only stay on the surface for silicone products? Silica gel products are essentially the material is silica gel, and silica gel is also graded, such as: medical grade silica gel, industrial grade silica gel, high temperature resistant silica gel, food grade silica gel, and we use in life of silica gel products material is food grade silica gel.

so do you know how to identify food grade silicone? Today small edits teach you a few tips, learn these moves easily handle food grade silica gel identification.

Tip 1: Smell and smell. The silicone products close to the nose to smell, the pungent smell is ordinary silica gel, vice versa is food grade silica gel. Common silica gel with pungent smell, belong to non-environmental silicone. And food grade silica gel is non-toxic and tasteless, belong to environmental protection silica gel.

Tip two: pull hard. Take the silicone tube for example, hold the two ends of the silicone tube with the hand, pull hard in the opposite direction, if pull white and can smell pungent taste, it is ordinary silica gel, on the contrary, food grade silica gel. (Sometimes it doesn't whiten, because the manufacturer produces by-products in the vulcanization process, so there will be a faint smell, but also food grade silica gel, which does not affect the quality of the product, and the smell can be eliminated by itself).

Tip three: baking. In addition to special silica gel, generally ordinary silica gel temperature resistance can only reach 150 degrees, and food grade silica gel can withstand high temperature 250 degrees, short time temperature can reach 350 degrees.

Tip 4: Require manufacturers or businesses to improve FDA food-grade certification.

The food grade silica gel has the characteristics of non-toxic and tasteless, high temperature resistance, stable chemical properties and high transparency. And the performance of ordinary silica gel is not so good, the use of such silica gel products will not only have a great smell, but also over time will appear yellow or dark lines and other phenomena.

Although said that now manufacturers generally do not use ordinary silica gel as food grade silica gel to deceive customers, but if we can learn how to identify food grade silica gel method, have their own discrimination ability, mother is no longer afraid that I buy poor performance and environmental protection of silica gel products.
