What is the difference between food grade silicone products and ordinary silicone?

What is the difference between food grade silicone products and ordinary silicone, in daily life, silicone products are everywhere, from kitchen utensils to baby products, silicone figure is everywhere. However, silicone is also divided into food grade and ordinary grade, and there are significant differences between the two in terms of material, application field and safety.

1. Differences in raw materials
Food-grade silicone: The raw materials used strictly comply with national food safety standards, do not contain toxic and harmful substances, to ensure that the product will not produce pollution when in contact with food
Ordinary silica gel: a wide range of raw materials, may contain certain harmful substances, is not suitable for direct contact with food.
2. Differences in production process
Food-grade silicone: In the production process, there are strict requirements for the production environment and equipment cleanliness to ensure product safety and health.
Ordinary silica gel: The environmental requirements in the production process are relatively loose, which may lead to a certain amount of impurities in the product.
3. Security differences
Food grade silicone: in line with food safety standards, can be directly in contact with food, used to make kitchenware, baby products, etc.
Ordinary silicone: may contain harmful substances, not suitable for direct contact with food, mainly used in industrial, home and other fields.

4. Temperature resistance difference
Food grade silicone: A wide range of temperature resistance, can be used between -40 ° C and 200 ° C, suitable for a variety of cooking environments.
Ordinary silica gel: the temperature resistance is relatively poor, and the maximum temperature resistance is generally about 150℃.
5. Service life difference
Food grade silicone: Because of its pure material, it is not easy to age and has a long service life.
Ordinary silica gel: because it contains a certain amount of impurities, it is easy to age and has a relatively short service life.
6. Price difference
Food grade silicone: Due to the high cost of raw materials and production, the price is relatively high.
Ordinary silica gel: raw materials and production costs are low, and the price is relatively low.

There are obvious differences between food-grade silicone products and ordinary silicone in raw materials, production process, safety, temperature resistance, service life and price. When choosing silicone products, the appropriate silicone material should be selected according to the use and use environment to ensure product quality and personal safety.
