The silica gel mold used for food generally meets the food grade standard and can be directly contained in the mouth. It is generally non-toxic and can be used with confidence.

Silica gel is a highly active adsorption material. The color of silicone rubber is white and opaque. It is an amorphous substance, insoluble in water and any solvent, non-toxic and tasteless, with stable chemical properties. It does not react with any substance except strong base and hydrofluoric acid. High adsorption performance, good thermal stability and stable chemical properties.

Because of its good stability and special resistance to high and low temperatures, silica gel can be heated in a microwave oven at high temperatures without deformation or releasing toxic substances, or it can be stored in a cold storage room.

Silica gel is close to human skin in texture, non-toxic and odorless, so pacifiers made of silica gel for children are also very healthy, and good silica gel has an automatic disinfection function, does not touch stains, and is easy to clean. Nowadays, many fashionable families use silica gel kitchenware, because it can cook completely in microwave ovens, which saves time and, more importantly, does not produce lampblack.

Raw materials of silica gel mold:
Silica gel is more and more popular because of its good environmental protection performance. To understand the silicone mold knowledge, you have to start from the silicone raw materials.

1. Raw materials of silica gel kitchenware can be divided into ordinary silica gel and meteorological silica gel according to performance
Common silica gel, also known as precipitated silica gel
Color: translucent, milky white, light yellow, gray, etc.
Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, etc., commonly used between 40 ° and 70 °.
Density: 1.1-1.12g/cm3
Elongation: 400%
Usage: The middle and low grade silicone products such as mobile phone buttons, miscellaneous parts and conductive adhesive are mostly used.

Weather gel, also known as pure silica gel
Color: transparent.
Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, etc., commonly used between 40 ° and 60 °.
Density: 1.1-1.12g/c ㎡
Elongation: 600% - 700%
Features: This material has good transparency and strong tensile resistance. High cost
Use: Silicone tube, protective sleeve and other high-grade products that need high elasticity.
2. Silica gel raw materials can be divided into solid silica gel and liquid silica gel according to their physical properties.
Is the silicone mold toxic? Everyone can use it with confidence when using some silicone products. The safety of silicone molds used today is very high, and they are also in line with national security. You can rest assured when using them. Don't worry too much. After all, manufacturers are responsible for us, especially silicone products used by children.
