Recently, one of the most frequently heard topics in life, that is, the choice of silicone products must choose food-grade silicone products, so that it is safe to use, it seems that people are becoming more and more aware of this, which is a good thing.
However, people do not know what food-grade silicone is?
Not all the products in the market are made of food-grade silicone.
Today, I will explain to you what is food-grade silicone products.
First of all, I would like to introduce the concept: food-grade silica gel products are an abbreviation of inorganic polymer colloidal materials made from silicic acid condensation, the main component is SiO2 ·nH2O, its content is more than 98%, it has the characteristics of non-toxic and tasteless, stable chemical properties, and does not react with any acid-base salt except caustic alkali and hydrofluoric acid.
Furthermore, in terms of the characteristics, properties and uses of food-grade silica gel:
1. The main characteristics of food-grade silicone products:
Non-toxic, odorless, transparent and non-yellowing.
Soft, elastic, kink-resistant and non-deformed.
Non-cracking, long service life, cold and high temperature resistance.
It has higher tear strength and superior electrical performance.
It has the advantages of high transparency, tasteless, non-yellowing, non-frosting, etc., especially to solve the problem of black hose frosting and blue products fading. Soft, high tear resistance, high insulation, wear resistance, high temperature resistance, flame retardant type, aging resistance, environmental protection, tensile type, stable performance and so on.
Second, the properties of food-grade silicone products:
1. Food grade silica gel is a kind of environmentally friendly silica gel, which is non-toxic, odorless and transparent.
2. Soft, flexible and resistant to kink and deformation.
3. Non-cracking, long service life, cold and high temperature resistance.
4. It has higher tear strength and superior electrical performance.
5. no yellowing at room temperature, no frosting, no whitening, no fading, no scale and no peculiar smell in the water for a long time.
III. Main uses of food-grade silicone products.
At present, it is mainly used for food double mold, chocolate mold, candy mold, precision casting, carbon fiber composite material, food cake mold, craft ceramics, printing, human organ cloning, household appliances, lighting products, silicone ice grid, silicone pacifier.
As people pay more and more attention to food-grade silicone products, it is believed that food-grade silicone will appear in many places.
After reading my description, do you know more about food-grade silicone?
Do you have a better understanding.
