Food-grade silicone this seemingly strange name, with the frequent emergence of maternal and child products, we also began to gradually pay attention to it.
1) as a kind of application in the pacifier, bottle, cup, placemat, bib, bowl, plate, cup, Food Grade Silicone Rubber spoon and other series of infant supplies;
2) Food Grade Silicone Rubber West Point baking series of tools and molds;
3) kitchen use of various types of equipment;
4) human organ cloning, beauty products;
5) all kinds of civilian, industrial products.
More products on the new materials, its wide range of applications, it is no doubt that food-grade silicone in the end what is it?
Food grade silica gel is made of silicic acid polycondensation of inorganic polymer colloidal material, the main component is SiO2-nH2O, its content in more than 98%, non-toxic and tasteless, chemical stability, in addition to normal caustic and hydrofluoric acid , Food Grade Silicone Rubber And does not react with any acid and alkali salt.
Can withstand 220 ℃ high temperature, can be used in the microwave oven, the human body without any side effects.
Compared to other materials, with safer and more healthy features.
For example, common plastic in the production must be added to a large number of antioxidants, plasticizers, stabilizers, these additives are harmful to the human body, and plastic in high temperature conditions will make environmental hormones exudate and in the body fat Accumulate in the organization.
In simple terms, food-grade silicone has a strong stability properties, and more in line with health and safety requirements. In fact, in the ordinary people home has a trace of food-grade silica gel, Food Grade Silicone Rubber the most common is the pressure cooker for sealing the gasket, easy to clean and non-toxic harmless.
1. Non-toxic, odorless, transparent, non-yellowing;
2. Soft, flexible, resistant to kink without deformation;
3. Food Grade Silicone Rubber No cracking, long life, cold and high temperature;
4. High tear resistance, high insulation, wear resistance, high temperature, flame retardant, anti-aging, environmental protection, tensile type, stable performance and so on.
The concept of food-grade silica is very vague, there is no mature industry standards to limit what is food-grade silicone. According to the popular explanation on the current network, food grade silica gel consists of two parts: one is the main component of SiO2 • nH2O inorganic silica gel, Food Grade Silicone Rubber the other part is synthetic silicone rubber. In our current understanding, food grade silicone is silicone and synthetic silicone rubber and food related to the use of silicone. Food grade silica gel needs to meet a variety of food safety standards.
The inorganic silica gel, which is mainly composed of SiO2 • nH2O, is an inorganic high molecular colloidal material obtained by polycondensation of silicic acid. SiO2 • nH2O content of 98% or more, non-toxic and tasteless, stable chemical properties, in addition to normal caustic and hydrofluoric acid, and not any acid and alkali salt reaction. Because it is a colloidal structure, it has many micropores and a large specific surface area. The silica pore size is about 8-10nm, the specific surface area of 300-500m2 / g, and the surface of hydrophilic, water has a strong absorption capacity, in the case of high humidity water up to 80% -100% of their own weight The So the silica gel can be used as food, pharmaceutical external desiccant.
After refining the silicone and food products can be mixed with the amount of food directly to ensure that the food is dry and food with food, and the human body without any side effects. There is also a food category of silicone called food purification silica gel, Food Grade Silicone Rubber the use of inorganic silica gel surface adsorption force to get rid of impurities in the liquid. Food Silicone Rubber is a silicone rubber that is part of synthetic silicone rubber that meets food safety standards.
The silicone rubber is a synthetic rubber, is dimethyl silicone and other silicone monomer polymerization of linear polymer elastomer, referred to as SIR. The macromolecular backbone is a Si-O unit, and the monovalent organic group is a pendant group, and the general formula is as follows: wherein R, R 'and R' 'are organic groups such as methyl, vinyl, phenyl , Trifluoropropyl, etc., the actual operation of the R, R ', R "choice to consider the group of biological inertia, to ensure that meet certain parameters, harmless to the human body. M, n is the degree of polymerization, is a wide range of changes in the integer.
Food grade silica gel Excellent use of convenience is mainly used for food complex, making a variety of food-related equipment, the production of medical equipment and food-related transport packaging.
