Food Grade silica gel is made from silicate inorganic polymer gel material condensation, the composition is silica, its content is more than 98%, non-toxic tasteless, chemical stability, food grade silicone tube In addition to hydrofluoric acid environmental stringent requirements, and any acid-base salt does not occur. Food Grade Silicone Rubber Because it is a colloid structure, there is a lot of micropore and large specific surface area. Food grade silica gel pore size of about 8 to 10 nm, than the surface area of 300-500 square meters/grams, and surface water, water has a strong absorption capacity, high humidity conditions of water absorption capacity can reach more than 80% to 100% of the weight. So food-grade silica gel can be used for food, drugs and external desiccant. Food grade silicone rubber is a refined non-toxic product, which can be directly mixed with food and medicine to ensure that food is dried and eaten together with food, without any side effects on the human body. Main performance A. Non-toxic, odorless, high transparency, yellowing; b。 Soft, good elasticity, resistance to kink deformation; C。 No cracking, long service life, Food Grade Silicone Rubber cold resistance and high temperature; D。 Higher tearing strength and superior electrical properties, it has a high degree of transparency, tasteless, no yellowing of the advantages, not spray cream, especially to solve the black hose cracking, blue products fade, soft, high tearing, high insulation, wear resistance, high temperature, flame retardant, anti-aging, environmental protection, tensile type, Food Grade Silicone Rubber stable performance and so on.
It is made by the condensation of silicic acid inorganic macromolecule colloid material, the main ingredient is SIO2·NH2O, its content is above 98%, non-toxic tasteless, chemical performance is stable, Food Grade Silicone Rubber in the normal except caustic and hydrofluoric acid, do not react with any acid-base salt. Because it is a colloidal structure, it has many pores and a large surface area. Edible silica gel aperture about 8-10nm, specific surface area 300-500m2/g, and surface hydrophilic, Food Grade Silicone Rubber water has a strong absorption capacity, in the case of high humidity, its water absorption can reach 80%-100% of its own weight. So food-grade silicone can be used as food, medicine, external desiccant. Since the edible silica gel is refined and sterilized, Food Grade Silicone Rubber can be combined with the food and drug demand to ensure that the food is dried and eaten together with food, without any toxic side effects on the human body.
Main characteristics of food grade silica gel
1. Non-toxic, odorless, high transparency, yellowing;
2. Soft, good elasticity, resistant to kink and deformation;
3. No cracking, long service life, cold resistance and high temperature;
4. With higher tearing strength and superior electrical properties;
Food grade silica gel with high transparency, tasteless, do not change yellow, frost and other advantages, Food Grade Silicone Rubber especially to solve the black hose spray cream, blue products fade the problem, soft, high tear-resistant, high insulation, wear resistance, high temperature, flame retardant type, anti-aging, environmental protection, tensile type, stable performance and other advantages.
Food-grade silica gel is widely used in coffee pots, water heaters, bread machines, disinfection cabinets, drinking fountains, kettle, hot bucket, rice cooker, frying pan, fruit pulp machine, burning equipment and other mechanical products, machinery, electrical, electrical and other industries. Such as: Drinking fountains, coffee pots, beauty salons equipment and lighting products protective sleeve; fire-retardant silicone tube: With flame-resistant, high pressure, high temperature and environmental characteristics. Mainly used in food complex mold, chocolate mold, candy molds, precision casting, as well as carbon fiber composite materials, food cake mold, process ceramics, Food Grade Silicone Rubber printing, human organ cloning, household appliances, lighting products, silicone ice lattice, silicone nipple.
