Food grade silicone is a special material with a wide range of applications. It is made from high-purity silicon raw materials, which have undergone special treatment and production processes. Food grade silicone has been widely used in the food industry due to its excellent heat resistance, cold resistance, chemical corrosion resistance, as well as excellent elasticity and insulation properties.
Food grade silicone is divided into different grades to meet the needs of different food safety standards. According to the requirements of relevant national standards, food grade silicone is divided into different grades such as food grade A, food grade B, and food grade C. The classification of these levels is mainly based on the content of residual harmful substances in silicone materials and the safety requirements for human health.
Food grade A-grade silicone is the highest grade of food grade silicone, with a very low content of residual harmful substances, and has undergone strict testing and certification. It is suitable for products that come into direct contact with food, such as food molds, baking utensils, baby bottles, etc. Food grade A-grade silicone has excellent high-temperature resistance and can withstand high-temperature baking without releasing harmful substances.
Food grade B-grade silicone is a second highest grade of food grade silicone, with a slightly higher content of residual harmful substances compared to food grade A-grade silicone, but still meets the requirements of food safety standards. It is suitable for products that come into indirect contact with food, such as sealing caps, sealing rings, food packaging, etc. Food grade B-grade silicone has good sealing performance and chemical corrosion resistance, which can effectively protect the freshness and quality of food.
Food grade C-grade silicone is the lowest grade of food grade silicone, with a relatively high content of residual harmful substances, but still within the safe range. It is suitable for products that have no direct contact with food, such as oven mats, baking tray mats, etc. Food grade C-grade silicone has good heat and cold resistance, and can maintain stability in high and low temperature environments.
In summary, food grade silicone plays an important role in the food industry as a safe and reliable material. Different levels of food grade silicone are suitable for different food contact products, ensuring food safety and quality. As people's attention to food safety continues to increase, the demand for food grade silicone will also continue to increase. In the future, food grade silicone will continue to play an important role in the food industry and continuously improve its product grade to meet people's higher requirements for food safety.
