Is the Silicone Mold Toxic?

- May 05, 2020-

Silicone molds are some mold glues specially made for crafts. It has many characteristics, with high corrosion resistance and high temperature resistance. The raw materials for silicone molds are very safe, and the environmental protection properties are also very good. We are more and more loved by us. There are already many silicone products. We will see such silicone products in many areas of our lives. So are silicone molds toxic?

Round and rectangular


Silicone products can be seen everywhere in our daily life. Silicone molds are used in many places, such as toys for children, stationery, dentures, gifts, etc. Silicone is needed. So are silicone molds toxic? People want to understand the problems in this regard.


Silicone molds for food generally meet food-grade standards and can be directly contained in the mouth. They are generally non-toxic and can be used with confidence


Silica gel is a highly active adsorbent material. The color of silicone rubber is white and opaque. It is an amorphous substance. It is insoluble in water and any solvents. It is non-toxic and odorless. It has stable chemical properties. The substance reacts. High adsorption performance, good thermal stability, stable chemical properties


Silica gel can be heated in a microwave oven at high temperature without deformation or release of toxic substances because it has good stability and is particularly resistant to high and low temperatures. It can also be stored in the refrigerator for refrigeration.


Because the texture of silicone is relatively close to human skin, and it is non-toxic and odorless, the pacifiers made of silicone for children are also very healthy, and good silicone has automatic disinfection function, does not stain, easy to clean, and now many fashionable families are Silicone kitchen utensils are used, because it can be completely cooked in a microwave oven, which is more time-saving and more importantly, it does not produce oil fumes.


Raw material for silicone mold


Silica gel is more and more popular because of its good environmental performance. To understand the knowledge of silicone molds, it is necessary to start with silicone raw materials.


1. The raw materials of silicone kitchen utensils can be divided into ordinary silica gel and meteorological silica gel according to performance


Ordinary silica gel is 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: More commonly used are mobile phone buttons, miscellaneous parts, conductive adhesives and other low-end silicone products.


Meteorological glue, also known as pure silicone


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 its good transparency and strong tensile strength. High cost


Uses: Silicone tube, protective cover and other high-end products that require high elasticity.


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


Is the silicone mold toxic? Everyone can use it with ease when using some silicone products. The safety of the silicone molds currently used is very high, which is also in line with national security. Everyone can be assured when using it. Don't worry too much, after all, the manufacturer is responsible for us, especially the silicone supplies used by children.
