Rubber is a kind of soft rubber material that we all know. It can be seen in many industrial environments, and silicone and rubber make many friends can not identify their differences, Laymen often mistake silicone for rubber material, and the real silicone material will be mistaken for latex material, so not to mention the grade of silicone and the difference. Silicone has industrial grade, food grade, medical grade, do you know the difference between them?
Silicone in all soft colloids is one of the best performance materials, it is more comprehensive in all aspects of the characteristics of high quality, so many industries have chosen to use it as the main body or spare parts, but we are difficult to use the naked eye to distinguish silicone products belong to the ordinary silicone material or food grade silicone material.We can use different skills to identify, For example, when the product is stretched and bounced back, the ordinary silicone will appear white mist on the surface of the stretching point, while the food-grade silicone will not produce white mist phenomenon when stretched.
Silicon is followed by combustion, ordinary silica gel material combustion will appear white smoke, powder particles after product combustion is big and easy to break, and food grade silica gel will also appear this phenomenon, but food grade silica gel powder will be fine, and not easy to break, combustion time is longer than ordinary silica gel.
So when it comes to identifying them, you can basically pull on your hand and tell whether the product is food grade or regular grade. At present, food-grade silicone materials are mainly used in life where there is more contact with the body and skin, such as silicone kitchenware :washing gloves ,ice comparment, dishwashing brush. silicone daily necessities: outdoor portbale coffe cup, collapsible kettle, beach bag silicone baby products: baby dinner plates, food bib silicone cosmetic products: face mask bowl, silicone toys
