With the arrival of summer, silicone molds have become popular, because some children like to eat snow bars, so they need to use this silicone mold to make snow bars by themselves. Now there are more and more silicone products, and they are popular in various industries. There are more and more daily necessities containing silicone, such as toys, gifts, stationery, dentures, etc. Even the pacifiers on the baby bottles are made of silicone rubber. Therefore, people who do not understand the nature of silicone begin to panic. Will silicone products affect human health?

Silicone molds for food generally meet food-grade standards and can be directly placed in the mouth. They are 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, and has stable chemical properties. Except for strong alkali and hydrofluoric acid, it is not compatible with any substances react. High adsorption performance, good thermal stability and stable chemical properties.

Because of its good stability and high temperature and low temperature resistance, silica gel can be heated in a microwave oven at high temperature without deforming or releasing toxic substances, and it can also be refrigerated in a refrigerator. Because of its texture close to human skin, and non-toxic and odorless, silicone pacifiers for children are also very healthy, and good silicone has automatic disinfection function, no stains, easy to clean, and now many fashionable families are Use silicone kitchen utensils, because it can be cooked completely in a microwave oven, which is more worry-free and time-saving, and more importantly, it will not produce oil fumes.

Raw material of silicone mold:

Silicone is more and more popular because of its good environmental performance. To understand the knowledge of silicone molds, you must start with silicone raw materials.

1. The raw materials of silicone kitchenware can be divided into ordinary silica gel and meteorological silica gel according to their performance.
Ordinary 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°-70°.
Density: 1.1-1.12g/cm3
Elongation: 400%
Uses: It is mostly used in low-grade silicone products such as mobile phone buttons, miscellaneous parts, and conductive glue.

Meteorological glue, also known as pure silica gel
Color: Transparent.
Hardness: 30°, 40°, 50°, 60°, 70°, 80°, etc., commonly used between 40°-60°.
Density: 1.1-1.12g/c㎡
Elongation: 600%-700%
Features: Due to the good transparency and strong tensile strength of this material. high cost
Uses: Silicone tubes, protective sleeves and other high-end products that require high elasticity.

2. Silica gel raw materials can be divided into solid silica gel and liquid silica gel according to their physical properties.

Are silicone molds toxic? Everyone can use it with confidence when using some silicone products. The safety of the silicone molds used now is very high, and it is also in line with national security. You can rest assured when using it. Don't worry too much.
