While silicone products enrich our daily lives, we all have some doubts about its safety, especially kitchen silicone products and silicone products for babies, where safety is the topic we are most concerned about.

Silicone products are essentially made of silicone, and silicone is also graded, so we often have this question: Is the silicone product I bought really food-grade silicone? How can I identify food grade silicone? Not anxious, the following Cushman & Wakefield Electronics will introduce you to a few methods, simple and practical:.

  Method 1, ask the smell of the product, there is a pungent smell is ordinary silica gel, and vice versa is food grade silica gel. Ordinary silicone with pungent smell is not environmentally friendly silicone. Food-grade silicone is non-toxic and tasteless, is environmentally friendly silicone.
  The second method, baking, general ordinary silica gel temperature up to 150 degrees, while the food-grade silica gel can withstand high temperature 250 degrees, a short period of time can be up to 350 degrees. Of course, except for special silicone.
         Method three, pull, to silicone tube for example, pinch the two ends of the silicone tube, pull hard in the opposite direction, if pulled up white and can smell the pungent smell, it means that it is ordinary silicone, on the contrary, it is food-grade silicone. (Sometimes it will not be white when pulled up, because the manufacturer has by-products in the production of vulcanization process, so there will be a faint smell, but also food-grade silicone, which will not affect product quality, and the smell can be eliminated by itself).

  Food grade silicone is non-toxic, odorless, high temperature resistant, chemically stable, and highly transparent, and the silicone products made will not turn yellow over time. The performance of ordinary silicone is not so good, and the products made with this kind of silicone will not only have a great odor, but also appear yellowing or dark lines with the growth of time.

Generally speaking, regular manufacturers will not use ordinary silicone to fool customers, but we can identify the food-grade silicone themselves, their own use of the heart is more secure.
