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, Food Grade Silicone Rubber 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, resistant to kink without deformation;
3. No cracking, long life, cold and high temperature;
4. Has a higher tear strength and superior electrical performance;
It has 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, Food Grade Silicone Rubber stable performance and so on.
Food grade silica gel use
Widely used in coffee pots, water heaters, breadets, disinfection counters, drinking fountains, kettle, iron, rice cookers, frying pan, pulp machine, gas appliances and other mechanical products, machinery, electrical appliances, electrical and other industries. Such as: drinking fountains, coffee pots, Food Grade Silicone Rubber 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, 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, Food Grade Silicone Rubber do not spray cream, do not spit white, do not fade, for a long time no water in the water, no smell;
