The seemingly unfamiliar name of food-grade silicone products, as they appear frequently in maternal and child products, has gradually begun to attract attention. As a new type of material used in nipples, baby bottles, cups, brushing teeth, and even spoons, its wide application level and the enthusiasm of merchants eagerly advertised, it is undoubtedly, what exactly is food-grade silicone products? Special visits to related experts, to find out.
According to experts, food-grade silicone products are inorganic polymer colloidal materials made of polycondensation of silicic acid. The main component is SiO2 • nH2O, which has a content of 98% or more, is non-toxic and odorless, has stable chemical properties, and removes caustic alkali under normal conditions. In addition to hydrofluoric acid, it does not react with any acid-base salts. It can withstand high temperatures of 220°C and can be used in microwave ovens without any side effects to the human body. It is safer and healthier than other materials. For example, common plastics must be added with a large amount of antioxidants, plasticizers, stabilizers, etc., which are harmful to the human body. Moreover, plastics will exude environmental hormones and cause fat in human body under high temperature conditions. Accumulated in the organization. In simple terms, food grade silicone products have strong stability properties and are more in line with health and safety requirements. In fact, traces of food-grade silicone products have been found in the homes of ordinary people. The most common is the gasket used for sealing in pressure cookers, which is easy to clean and non-toxic.
At present, the food grade silicone products mainly involved in the market are mainly classified into drug-grade silicone products and food-grade silicone products, but they need to be certified by the State Food and Drug Administration. The infant products on the market in China generally follow three national standards: China, the United States, and Europe. Experts suggest that at the time of purchase, it is necessary to understand what kind of standards the product is implemented in, and whether it is certified by the State Food and Drug Administration or a third-party testing agency to ensure that it is authentic.
With the rise of food-grade silicone products in foreign countries, their health and safety performance has been proven, and domestic manufacturers have begun to use plastic materials instead of the original ones. They are mainly used in maternal and child products, but some manufacturers also use the materials in innovative applications. In daily life supplies, such as cups, bowls, baking molds, steamers, etc. At the same time with the formation of other materials, the emergence of ceramic silica gel products, glass silica gel products and other material combinations. While being beautiful and durable, it also highlights the concept of healthy life and environmental health.
Experts said that replacing food grade silicone products with conventional materials has become a trend in the development and design of future life products. The popularization of low-carbon life concept also encourages everyone to develop and attach importance to environmentally-friendly materials. In the next few years, food-grade silicone products will become a common material for everyday life in every family.
