Silicone O-Rings are annular seals made of silicone material, which are widely used in occasions that require sealing and leak-proofing. Its basic function is to fill the gap between two contact surfaces through its elasticity and compressibility, thereby preventing the leakage of gas, liquid or other substances. The following is a detailed description of silicone O-Rings:

1. Material characteristics:

Silicone material: It is composed of siloxane (Si-O) polymer, with excellent temperature tolerance, chemical stability and biocompatibility.

Various colors: Common silicone O-rings are transparent or white, but different colors can also be customized as needed.

2. Temperature tolerance:

High temperature: Silicone O-rings can withstand extreme high temperature environments, usually with a temperature range of -60°C to +230°C, and some special varieties can withstand higher temperatures.

Low temperature: It can maintain elasticity and good sealing performance under low temperature conditions, suitable for use in cold environments.

3. Chemical resistance:

Silicone O-rings have strong anti-aging ability against water, oxygen, ultraviolet rays and most chemicals.

Silicone O-rings can also remain relatively stable in environments such as acids, alkalis, and solvents.

4. Sealing performance:

Small compression deformation: After being compressed, the deformation of the silicone O-ring is very small, and it has strong recovery ability and can maintain good sealing.

Anti-leakage: Through good compression adaptability, silicone O-rings can effectively prevent the leakage of air, liquid or gas.

5. Biocompatibility:

Due to its high purity and non-toxic properties, silicone O-rings are widely used in food processing, medical equipment, pharmaceutical industry, and baby products, etc., which need to contact the human body.

6. Aging resistance:

After long-term exposure to ultraviolet rays, ozone and high temperature, silicone O-rings can still maintain a long service life and excellent performance.

7. Application areas:

Food industry: used for food processing equipment, beverage equipment, etc.

Medical industry: commonly used for sealing of medical instruments, hemodialyzers and other equipment.

Chemical industry: used for chemical pipelines, chemical container sealing, etc.

Automotive industry: used for sealing in automobile engines and air conditioning systems.

Aerospace: Sealing applications in high temperature and high pressure environments.

8. Installation and maintenance:

Easy installation: Make sure the size of the O-ring matches the installation groove during installation to avoid uneven compression.

Avoid stretching: Avoid excessive stretching of the O-ring during installation to prevent cracking or loss of elasticity.

Cleaning: Check and clean the O-ring regularly to ensure its sealing and extend its service life.
