What are the common materials of silicone rubber products? What are their characteristics?

Silicone rubber products are widely used in all aspects of life, whether in industry, medical treatment, daily department stores, they can be seen everywhere. Do you know what common materials silicone rubber products have? What are their characteristics? Today, Aobo silica gel will popularize the relevant knowledge for everyone:

Silicone rubber is a kind of polymer elastic material with unique physical and chemical properties, its basic material mainly includes the following types:

1, methyl vinyl silicone rubber: ordinary silicone rubber is mainly composed of methyl and a small amount of vinyl silicone chain. This type of silicone rubber has good low temperature resistance and can usually remain in working condition at -55 ° C. After the introduction of phenyl, this low temperature resistance can reach -73℃, and its heat resistance is also quite outstanding, and it can work for a long time at 180℃.

2, phenyl silicone rubber: the introduction of phenyl can improve the high and low temperature resistance of silicone rubber.

3, fluorosilicone rubber: the introduction of trifluoropropyl and cyanide can enhance the temperature and oil resistance of silicone rubber.

The characteristics of silicone rubber products are as follows:

1, high and low temperature resistance: silicone rubber has a wide operating temperature range in all rubber, from -100℃ to 350℃. Specific silicone rubber varieties can withstand higher temperatures, such as low phenyl silicone rubber can remain elastic at 350 ° C.

2, aging resistance: silicone rubber has good resistance to ozone, oxygen, light and climate aging. Even if exposed to sunlight for a long time, its performance will not change significantly.

3, electrical insulation: silicone rubber has excellent electrical insulation properties, making it a commonly used material in the electronic and electrical field.

4, permeability: the oxygen permeability of silicone rubber is very high, which is true in synthetic polymers.

In general, these materials and characteristics of silicone rubber make it play an important role in many industries, from aerospace to medical, to kitchen supplies in daily life, silicone rubber is widely used and in-depth. When choosing silicone rubber products, understanding the properties of these materials can help you make a choice that is more suitable for your specific application.
