Not necessarily

Silicone rubber is not necessarily food grade, but there are food grade, environmental grade and medical grade. Food grade: Food grade silica gel refers to tableware and kitchen utensils that can be used for food packaging or food contact. Environmental protection grade: Environmental protection grade silicone rubber refers to silicone sealing strips for industrial products, doors and windows, silicone gaskets, silicone mobile phone cases, and thermal conductive silicone. Medical grade: Medical grade silicone rubber is higher than food grade silicone rubber, with medical grade silicone rubber material and harsh certification.

Food-grade silica gel is an inorganic polymer colloid material formed by condensation polymerization of silicic acid. Its content is over 98%, and it is non-toxic and tasteless, with stable chemical properties. Under normal conditions, it does not react with any acid or alkali except caustic soda and hydrofluoric acid. It can withstand the high temperature of 28℃, and can be used in a microwave oven without any toxic or side effects on human body. Compared with other materials, it is safer and healthier.

For example, a large number of antioxidants, plasticizers, stabilizers, etc. must be added in the production of common plastics. These additives are harmful to human body, and plastics will make environmental hormones seep out and accumulate in human adipose tissue at high temperature. Simply put, food-grade silica gel has strong stability and is more in line with the requirements of healthy and safe life.

advantages of food-grade silicone rubber daily necessities compared with other materials

1. High requirements for raw materials

The requirements for raw materials and production and molding are all high requirements, such as environmental protection requirements: the raw materials of silicone rubber are highly transparent and high purity, which can pass many tests and certifications worldwide, such as REACH, RoHS, CCC, LFGB or FDA. Performance requirements of raw materials:

2. The process requirements are high

The products formed by mixing the corresponding color glue and high-efficiency anti-yellowing vulcanizing agent can meet the standards of food-grade silica gel and the molding process requirements.

3. The requirements of environmental protection are high

In order to achieve safety, green and environmental protection, the hygiene of the production environment and the performance of the machine should be adjusted accordingly during production, so as to keep it free of impurities and foreign bodies and vulcanize at high temperature.
