Views:5     Author:Site Editor     Publish Time: 2018-11-19      Origin:Site

Food grade silicone used in food is an inorganic polymeric colloid material formed by polycondensation of silicic acid. The main ingredient is SiO2·nH2O, with a content of over 98%, no toxicity, no taste and stable chemical performance. Under normal conditions, it does not react with any acid-base salt except caustic soda and hydrofluoric acid.Because it is a colloidal structure, it has many micropores and a large specific surface area.

Food Grade Silicone Stopper

 The pore size of edible Food grade silicone is about 8-10nm, the specific surface area is 300-500m2/g, and the surface is hydrophilic and has strong absorption capacity for water. In the case of high humidity, its water absorption capacity can reach more than 80-100% of its own weight.Therefore, the food grade silicone can be used as an external drying agent for food and medicine.As the consumption of silica gel is refined and sterilized, it can be mixed with food and medicine according to the required amount to directly ensure that the food is dry and consumed together with food, and there are no toxic and side effects on the human body.


Main features of food grade silicone:
1. Non-toxic, odorless, high transparency and non-yellowing;
2. Soft and elastic; resistant to kink and deformation;
3. No cracking, long service life, cold and high temperature resistance;
4. Higher tear strength and excellent electrical performance;
It has the advantages of high diaphaneity, odourlessness, changeless yellow and no frost, especially solve the problem of black rubber tube frosting and blue products fading, soft, high tear resistance, high insulation, wear resistance, high temperature resistance, flame retardant, aging resistance, environmental protection, tensile and stable performance.


The application of food grade silicone:
It is widely used in coffee pot, water heater, bread machine, disinfection cabinet, water dispenser, water kettle, iron pan, rice cooker, oil fryer, fruit pulp machine, fuel and other mechanical products, machinery, electrical appliances, electrical and other industries.Protection covers for water dispensers, coffee POTS, beauty and hair care equipment and lighting products;Fireproof silica gel pipe: it is characterized by flame resistance, high pressure resistance, high temperature resistance and environmental protection.Mainly used in food mold, chocolate mold, candy mold, precision casting, as well as carbon fiber composite materials, food cake mold, process ceramics, printing, human organ cloning, household appliances, lighting products, Silicone ice cream, silicone rubber pacifier.
