The chemical properties of silicone rubber are mainly manifested in the following aspects:



1. Non toxic, odorless, and non corrosive
Silicone rubber is a non-toxic and odorless material that does not have harmful effects on the human body or cause corrosion to objects in contact. This characteristic enables silicone rubber to be widely used in fields such as medicine, food, and daily chemicals.

2. Chemical inertness
Silicone rubber has a high degree of chemical inertness, which means it is not easy to react with other chemicals. This property enables silicone rubber to remain stable in various chemical environments and is not easily corroded or degraded.

3. Thermal stability and antioxidant properties
Silicone rubber has high thermal stability and antioxidant properties. The main bond of its molecule is composed of alternating silicon atoms and oxygen atoms (-- Si-O-Si -). The bond energy of the silicon oxygen bond is as high as 370kJ/mol, which is much higher than the carbon carbon bonding energy of general rubber (about 240kJ/mol). This is one of the main reasons why silicone rubber has high thermal stability. Therefore, silicone rubber can maintain stability in its physical and chemical properties over a wide temperature range (-100 to 350 ° C).

4. Weathering resistance
Silicone rubber also has good weather resistance and can be used for a long time in harsh outdoor weather conditions without being prone to aging, cracking, or deformation.

5. Oil and solvent resistance
Some special silicone rubbers also have excellent oil and solvent resistance, which can maintain their stability when in contact with chemical substances such as oils and solvents.

6. Electrical insulation
Silicone rubber has excellent electrical insulation performance and can be used as insulation components in electrical equipment to ensure the safe operation of electrical equipment.

7. Breathability
Silicone rubber also has a certain degree of breathability, which makes it perform well in certain applications that require breathability, such as medical breathable films.

8. Processability
Silicone rubber is easy to flow and process, and can be molded, rolled, and extruded at low energy consumption, improving production efficiency.

9. Other characteristics
In addition, silicone rubber also has excellent heat dissipation, ozone resistance, high transparency, tear strength, as well as excellent adhesion, fluidity, and demolding properties.

In summary, silicone rubber has been widely used in various fields due to its unique chemical properties, including but not limited to defense and military industry, medical and health, industrial and agricultural production, and people's daily lives.
