Introduction to Material for Food-grade Silicone Food Clip

Food-grade silicone

Food grade silica gel is an inorganic polymer colloidal material formed by the polycondensation of silicic acid. Its main component is SiO2·nH2O of more than 98%. It is non-toxic, odorless, chemically stable, and does not react with any acid or alkali salts except caustic soda and hydrochloric acid under normal conditions. Because it is a colloidal structure, it has a lot of micropores and a large specific surface area.

 

Food silica pore size is about 8-10nm, specific surface area 300-500m2/g. With a hydrophilic surface, it has a very good water absorption capacity, which under high humidity can reach 80%-100% of its weight or more. Therefore, food-grade silica gel can be used as an external drying agent for food and medicine. Because the food grade silica gel is refined and sterilized, it can be mixed with food and drugs directly to ensure the dryness of the foodstuffs after it is mixed with the required amount. It can be used with food. It has no toxic side effects on the human body, so it can be used to produce silicone food clips.

 

Main features

 

1. It is non-toxic, odorless, highly transparent, and non-yellowing.

 

2. It is soft, flexible, kink-resistant, and not easily deformed.

 

3. It is not easy to crack and has a long service life and is resistant to cold and high temperatures.

 

4. It has higher tear strength and superior electrical properties.

 

It has the advantages of high transparency, odorless, no yellowing, and no frosting. In particular, it solves the problem that black hose spray frosting, blue products will fade. Besides, it has the advantages of softness, high tear resistance, high insulation, abrasion resistance, high-temperature resistance, flame retardant, aging resistance, environmental protection, tensile stable performance, which makes it safe to be used on food clips.
