Project details

Organosilicon and nitrile O-rings are common sealing materials. Organosilicon is a compound with special properties formed by combining silicon atoms with oxygen atoms or carbon atoms, while nitrile is a copolymer of acrylonitrile (CH2=CHCN) and butadiene (CH2=CHCH=CH2). There are some differences in properties and applications between these two materials.

The main characteristic of organic silicon compounds is the presence of silicon oxygen bonds (Si O bonds) and carbon carbon bonds (C-C bonds) in their molecular structure. Among them, the silicon oxygen bond is stable and not easily attacked by chemical substances, and has high thermal and chemical stability. Therefore, organic silicon compounds are widely used in various demanding sealing and anti-corrosion environments, such as high temperature, high pressure, strong acid, strong alkali, high humidity, and so on.

Nitrile is a synthetic rubber with excellent oil resistance, chemical corrosion resistance, and weather resistance. The butadiene in its molecular structure gives it good elasticity and resilience, and can be used in various static and dynamic sealing situations. Nitrile O-ring is one of the most common sealing materials and is highly favored due to its low cost, wide application range, and good wear resistance.

Although both silicone and nitrile O-rings are excellent sealing materials, there are still differences in their performance and application fields. Organic silicon O-rings have better resistance to high temperature, chemical corrosion, and weather, making them suitable for more demanding sealing environments. However, nitrile O-rings have lower costs and better wear resistance, making them widely used in some conventional sealing applications.

Overall, both silicone and nitrile O-rings are excellent sealing materials, and the choice of material to use depends on the specific application scenario and requirements. For situations that require high-performance sealing such as high temperature resistance and chemical corrosion resistance, silicone O-rings are a better choice; In some conventional sealing situations, nitrile O-rings are favored due to their lower cost and good wear resistance.
