The related introduction about food grade silicone tube
![]()
The food of the silicone tube has been rather vague concept, there is not yet a standard to define what is food silicone tube. According to the current network popular explanation, food silicone tube includes two parts: one part is the main component of inorganic silica gel for SiO2 nH2O, another part is the synthesis of silicon rubber. In our current understanding, related to the silica gel and food application of food grade silicone tube is the organic silica gel and synthetic silicon rubber. Food needs to meet a variety of food safety standards on silica gel.
The main component of food grade silicone rubber hose for inorganic silica gel SiO2 nH2O is inorganic polymer colloid material by condensation polymerization of silicic acid. SiO2 and nH2O content in the more than 98% non-toxic, tasteless, stable chemical properties, in the normal condition except caustic and hydrofluoric acid, without any acid salt from the reaction. Because it is a kind of colloidal structure, so it has many micro pores and large surface area. The silica gel pore size of about 8-10nm, 300-500m2/g specific surface area, and the surface hydrophilic, have strong absorption ability of water in wet condition, high self weight and the water absorption capacity of up to more than 80%-100%. So the silica gel desiccant as food, drugs for external use.
After refining the silica gel to the food and drugs according to the required amount of mixed directly after drying and ensure food and food eaten together, without any toxic side effect on human body. There is a class called food food silica gel purification by surface adsorption capacity of silica gel, silica gel to dispel inorganic impurities in liquid. Food silicon rubber is the silicon rubber part of synthetic silicon rubber to reach the food safety standards.
This kind of silicone rubber is a kind of synthetic rubber, is the linear polymer elastic body is composed of two methyl siloxane and other silicone monomer is polymerized, referred to as SIR. The macromolecular backbone is Si-O units, the unit price of organic groups as side groups, the general structure of type of figure, type in R, R, R '"for the organic moiety, the actual operation process of R, R' R", to be considered in the selection of groups of biologically inert, to ensure that meet certain parameters, harmless to the human body. M, n as the degree of polymerization, integer is changed in a wide range of.
Performance of food grade silicone tube high convenient use, mainly for food, utensils, complex mode making various food related production of medical utensils and food related transport packaging. Shenzhen Jiajie silica gel products factory production of food grade silicone tube has the advantages of high performance, high safety level certificate, quality assurance, safety and ease of use.
