Hello, everyone. I am the editor. With the further improvement of industrial level, more and more people will use a large number of silicone rubber products in their lives. The two most common silicone rubber products can be divided into ordinary silicone rubber products and food-grade silicone products.


Food-grade silicone rubber daily necessities have irreplaceable characteristics. First of all, non-toxic and odorless is the basic, and secondly, the service life and performance must be outstanding. Compared with other ordinary materials, the difference is that it is resistant to high temperature and does not deform, and has stronger toughness. For example, it will not be bumpy after falling, and it can be bent and kneaded for a long time. It is not sticky to oil stains, and it will not mold or change color after being placed for a long time. These characteristics are also incomparable to ordinary materials and other materials.


Silicone rubber is widely used in food. Various silicone rubber kitchenware and silicone rubber tableware can be produced, and they are absolutely passed quality inspection. In fact, there are traces of food-grade silicone rubber in ordinary people's homes. The most common one is the gasket used for sealing in pressure cookers, which is easy to clean and non-toxic and harmless. Its application in the kitchenware industry can be seen everywhere. Taking silicone rubber spatula as an example, its characteristics are that it can be bent and fit the bottom of the pot more closely. Its water-resistant, oil-resistant, non-stick pan and easy-to-clean characteristics are also loved by consumers. Silicone rubber pacifiers will not deform or produce odor even if boiled in boiling water. They have many advantages and have become the choice of many parents.


Do you know how to identify food-grade silicone rubber? Today, the editor will teach you a few tips. Learn these tips to easily identify food-grade silicone rubber.


Secret 1: Smell method. Put the silicone rubber product close to your nose and smell it. If there is a pungent smell, it is ordinary silicone rubber, otherwise it is food-grade silicone rubber. Ordinary silicone rubber has a pungent smell and is not environmentally friendly silicone rubber. Food-grade silicone rubber is non-toxic and odorless, and is environmentally friendly silicone rubber.


Secret 2: Pull hard. Take the silicone rubber tube as an example. Pinch the two ends of the silicone rubber tube with your hands and pull it in opposite directions. If it turns white and you can smell a pungent smell, it means it is ordinary silicone rubber, otherwise it is food-grade silicone rubber. (Sometimes it will not turn white when pulled up. Since the manufacturer generates by-products during the vulcanization process, there will be a faint smell, but it is also food-grade silicone rubber, which will not affect the product quality, and this smell can be eliminated by itself).


Secret three: baking method. Except for special silicone rubber, the temperature resistance of ordinary silicone rubber can only reach about 150 degrees, while food-grade silicone rubber can withstand high temperatures of 250 degrees and up to 350 degrees in a short time.


Secret four: Require manufacturers or merchants to improve FDA food grade certification.


Although manufacturers generally do not use ordinary silicone rubber as food-grade silicone rubber to fool customers, if we can learn how to identify food-grade silicone rubber. Right
