Silicone rubber is a kind of rubber products whose main chain is composed of silicon and oxygen atoms alternately. Usually, there are two organic groups on the silicon atoms. The common products are foamed silica gel, pacifier silica gel, food grade silica gel, liquid silicone rubber and so on.


Chinese science traceability reminder: silicone rubber composition analysis needs to pay attention to whether silica gel has been modified.


1、 Brief introduction of silicone rubber


Silicone rubber is mainly composed of silicon oxygen bond containing PE group and PE group. For example, the introduction of phenyl can improve the high temperature resistance and low temperature resistance of silicone rubber, and the introduction of some additives can improve the high temperature resistance and oil resistance of silicone rubber. Performance: rubber has excellent high and low temperature resistance, ozone resistance and atmospheric aging, also has good dielectric properties and good low temperature resistance. Foamed silicone rubber is a two-component room temperature vulcanized silicone rubber. Its color is white paste liquid. After vulcanization, it becomes a soft elastomer material. After vulcanization, it becomes a soft elastomer. It is light, soft, elastic, not easy to transfer heat, and has the functions of anti impact, reducing impact, heat insulation and sound insulation.


2、 Advantages of silicone rubber


1. The foaming silica gel in the silicone rubber has a high multiple, and the volume can be increased by 2-7 times after foaming.


2. It has excellent high and low temperature resistance, weather resistance, chemical stability and excellent biological inertia.


3. Silicone products are safe, environment-friendly, non-toxic, tasteless, non corrosive and non radioactive.


4. Good fluidity, fast curing speed and good demoulding performance.


5. It has excellent heat resistance, cold resistance, electrical insulation and flame retardancy.


6. Silicone rubber has good processability, good stability and good resilience.


7. It also has strong tear resistance, high resilience and processing performance.


3、 Composition analysis of silicone rubber formula


Silicone rubber is used in transportation vehicles such as automobiles or other industries such as chemicals and daily necessities. It is commonly used in the market as thermal insulation, sound insulation and shock proof materials, as well as cushion and mattress.
