Silicone rubber is not necessarily food grade, but can be classified into food grade, environmental grade, and medical grade. Food grade: Food grade silicone refers to the use on food packaging or tableware and kitchen utensils that come into contact with food. Environmental grade: Environmental grade silicone rubber refers to the application of industrial products, silicone sealing strips for doors and windows, silicone gaskets, silicone phone case covers, thermal conductive silicone, etc. Medical grade: Medical grade silicone rubber is higher than food grade silicone rubber, with medical grade silicone rubber materials and strict certification.

Food grade silica gel is an inorganic macromolecular colloidal material made by condensation of silicic acid. Its content is more than 98%. It is non-toxic, tasteless, and has stable chemical properties. Under normal conditions, except for caustic soda and hydrofluoric acid, it does not react with any acid, alkali or salt. It can withstand high temperatures of 280 ℃ and can be used in a microwave oven without any toxic or side effects on the human body. Compared to other materials, it has the characteristics of being safer and healthier.

For example, common plastics must be added with a large amount of antioxidants, plasticizers, stabilizers, etc. during production. These additives are harmful to the human body, and plastics can cause environmental hormones to seep out and accumulate in the adipose tissue of the human body under high temperature conditions. Simply put, food grade silicone has strong stability properties and is more in line with the requirements of healthy and safe living.

Advantages of food grade silicone rubber daily necessities compared to other materials
1. High requirements for raw materials
The requirements for raw materials to production molding are all high standards, such as environmental requirements: silicone raw materials are made of high transparency and purity, which can pass multiple global testing certifications, such as REACH, RoHS, CCC, LFGB or FDA. Raw material performance requirements:
2. High process requirements
The product can only meet the standards of food grade silicone and the molding process requirements by mixing the corresponding color adhesive and high-efficiency anti yellow vulcanizing agent
3. High environmental requirements

In order to achieve safety, green and environmental protection, corresponding adjustments should be made to the hygiene of the production environment and the performance of the machine during production by the manufacturer, ensuring that there are no impurities, foreign objects, high-temperature vulcanization, oven baking, product cleaning, and QC testing are all relatively strict.
