With the further improvement of industrial level, more and more people are using a variety of silicone rubber products in their daily lives. The two most common types of silicone rubber products can be divided into ordinary silicone rubber products and food grade silicone rubber products.
Food grade silicone daily necessities have irreplaceable characteristics. Firstly, they are non-toxic and odorless, and secondly, their lifespan and performance must be outstanding. Compared with other ordinary materials, the difference lies in their resistance to high temperature and deformation, stronger toughness, such as not bumping after falling, long-term twists and turns, kneading, non sticking oil stains, long-term storage without mold, discoloration, and other characteristics. This is also why ordinary materials cannot be compared to other materials.
The application of silicone rubber in food is very extensive, and various silicone rubber kitchenware and silicone rubber tableware can be produced, and they absolutely pass quality inspection. In fact, there is already a trace of food grade silicone rubber in ordinary people's homes, and the 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 kitchen utensils industry can be seen everywhere, taking silicone rubber shovels as an example. Its characteristics are that it can be bent and more closely fits the bottom of the pot. Its water resistance, oil resistance, non stick pot, and easy cleaning characteristics are also loved by consumers. Silicone rubber nipples, even when boiled in boiling water, do not deform or produce odors, and have many advantages, making them the choice of many parents.
Do you know how to distinguish food grade silicone rubber?
1. Smell the odor method. Bring the silicone rubber product close to your nose and smell it. The one with a pungent odor is ordinary silicone rubber, while the other is food grade silicone rubber. Ordinary silicone rubber has a pungent odor and is not environmentally friendly. Food grade silicone rubber is non-toxic and odorless, and belongs to the category of environmentally friendly silicone rubber.
2. Strong pulling method. Taking a silicone rubber tube as an example, hold both ends of the tube with your hand and pull it vigorously in the opposite direction. If it turns white and can still smell a pungent smell, it indicates that it is ordinary silicone rubber, while on the contrary, it is food grade silicone rubber. (Sometimes it won't turn white when pulled up, as the manufacturer produces by-products during the vulcanization process, resulting in a faint odor. However, it is also food grade silicone rubber, which will not affect product quality and can be eliminated by itself.).
3. Baking method. Except for special silicone rubber, ordinary silicone rubber can only withstand temperatures up to around 150 degrees Celsius, while food grade silicone rubber can withstand temperatures up to 250 degrees Celsius and can withstand temperatures up to 350 degrees Celsius in a short period of time.
4. Require manufacturers or merchants to improve FDA food grade certification.
