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 , And does not react with any acid and alkali salt. Food Grade Silicone Rubber Because it is a colloidal structure, it has many micropores and a large specific surface area. Edible silicone pore size of 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 its own weight of 80% -100% The So the food grade of silica gel can be used as food, pharmaceutical topical desiccant. As the edible silica gel is refined and sterilized, and food and pharmaceutical products can be mixed after the need to directly ensure the food dry and food with food, Food Grade Silicone Rubber and the human body without any side effects.
Main features of food grade silica gel
1. Non-toxic, odorless, high transparency, no yellowing;
2. soft, flexible, Food Grade Silicone Rubber resistant to kink without deformation;
3. No cracking, long life, cold and high temperature;
4. Has a higher tear strength and superior electrical performance;
Food-grade silicone with a high transparency, tasteless, not yellow, not spray cream, etc., in particular, to solve the black hose spray cream, blue products fade problems, soft, high tear, high insulation, wear resistance, High temperature, flame retardant, anti-aging, environmental protection, tensile type, stable performance and so on.
Food grade silicone is widely used in coffee pots, water heaters, breadets, disinfecting cabinets, drinking fountains, kettle, iron, rice cookers, frying pan, pulp machine, Food Grade Silicone Rubber gas appliances and other mechanical products, machinery, electrical appliances, electrical industry. Such as: drinking fountains, coffee pots, beauty salons and lighting products, protective clothing; fire silicone tube: a fire-resistant, high pressure, high temperature and environmental protection and so on. Mainly used for food mold, chocolate mold, candy mold, precision casting, and carbon fiber composite materials, food cake mold, craft ceramics, printing, human body cloning, Food Grade Silicone Rubber household appliances, lighting products, silica gel ice lattice, silicone pacifier.
Food grade silica gel performance
1, food grade silicone is a silicone silicone, non-toxic, odorless, high transparency;
2, soft, flexible, resistant to kink without deformation;
3, no cracking, long life, cold and high temperature;
4, with a higher tear strength and superior electrical performance;
5, at room temperature does not turn yellow, do not spray cream, do not spit white, do not fade, for a long time no water in the water, no smell;
Many customers purchase mixed silicone rubber will be directly called for procurement of environmentally friendly mixed silicone rubber, environmentally friendly mixed silicone rubber in our silicone industry in terms of professional terms in terms of food grade silicone. Food grade silica gel compared to ordinary mixing silicone rubber with non-toxic and tasteless, safe and reliable features, Food Grade Silicone Rubber can be directly in contact with the human body, so many foreign manufacturers will be directly named export-type silicone rubber.
Food grade silicone is currently widely used in daily necessities, of which we live in the mobile phone shell, baby bib, lid, plumbing, placemat, etc. are made of food grade silicone. At present in the industrial production process, some manufacturers in order to pursue quality, will use this food-grade silicone instead of the original ordinary type of silicone rubber.
How is food-grade silicone made? Food grade silica gel in the original basis of mixing silicone rubber by adding odorless curing agent or platinum vulcanizing agent produced, Food Grade Silicone Rubber and the general industrial use is made by adding double two curing agent. The difference between the two is that food-grade silicone in the production of molding will not produce odor, and can be directly in contact with the human body. Food grade silicone can be through the FDA international quality testing standards, generally have the ability to produce food grade silicone manufacturers are obliged to provide customers with food-grade silicone testing certification.
