High Transparency Of Food Grade Silica Gel

Aug 01, 2017

Food Grade silica gel is condensed from silicic acid inorganic macromolecule colloid material, the main ingredient is SIO2·NH2O, its content in more than 98%, non-toxic tasteless, chemical stability, in the normal in addition to caustic and hydrofluoric acid, not with any acid-base salt reaction. Food Grade Silicone Rubber 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, water has a strong absorption capacity, Food Grade Silicone Rubber 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, can be combined with the food and drug demand to ensure that the food is dried and eaten together with food, Food Grade Silicone Rubber without any toxic side effects on the human body.

Main Features

1. Non-toxic, odorless, high transparency, yellowing;

2. Soft, good elasticity, resistant to kink and deformation;

3. No cracking, long service life, Food Grade Silicone Rubber cold resistance and high temperature;

4. With higher tearing strength and superior electrical properties;

It has high transparency, tasteless, do not change yellow, frost and other advantages, 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, Food Grade Silicone Rubber stable performance and other advantages.


Widely used in coffee pots, water heaters, bread machines, disinfection cabinets, water dispenser, kettle, hot bucket, rice cooker, frying pan, fruit pulp machine, ignition 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, Food Grade Silicone Rubber 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, printing, human organ cloning, household appliances, lighting products, silicone ice lattice, silicone nipple.


1, food grade silicone silica gel is environmentally friendly, non-toxic, odorless, high transparency;

2, soft, good elasticity, resistance to kink deformation;

3, not cracking, long service life, cold resistance and high temperature;

4, with higher tearing strength and superior electrical performance;

5, the room temperature place does not change yellow, Food Grade Silicone Rubber does not spray the frost, does not spit white, does not fade, the long water without scale, is no different flavor;

Food Grade Silica Gel operation method

1. Take A and B in proportion to the standard stirring evenly, Food Grade Silicone Rubber and then put into the vacuum machine suction bubble, general operation time about 10-15 minutes.

2. After pouring the mold, heating to 60 ℃ 2-3 hours, cooling, Food Grade Silicone Rubber solidification molding can be taken out. If the temperature is 120° only needs more than 10 minutes to be able to shape.

3. Before use, please take a small number of experiments to master its operating skills to avoid waste.
