Silica gel O-ring seals adopt an O-shaped cross-section design. When the silicone O-ring is under pressure, its cross-section can promote uniform pressure distribution. From the perspective of mechanical principles, uniform pressure distribution avoids stress concentration. Stress concentration is like continuously applying excessive force to a weak point, which can easily cause material damage. The O-shaped cross-section design resolves this hidden danger and reduces the risk of damage caused by stress concentration. O-rings can adapt to various complex shapes of sealing surfaces, and can adaptively deform according to the shape of the sealing surface to achieve all-round close contact.
Significant advantages of silicone materials
Silicone materials give O-rings many unique properties. Silicone has good elasticity and resilience. When under pressure, its molecular structure can be flexibly adjusted to deform the O-ring, thereby better filling the extremely small gaps between the sealing surfaces. This deformation and filling ability enables the O-ring to form a closer fit with the sealing surface under pressure to prevent the leakage of the medium. Silicone itself is non-toxic and odorless. This feature enables it to be widely used in fields with extremely high requirements for hygiene and safety. After a number of rigorous tests and certifications, silica gel O-ring seals meet food grade requirements, which means that they can directly contact food and will not have any adverse effects on the quality and safety of food.
Playing a key role in multiple fields
In the field of mechanical equipment, silica gel O-ring seals can prevent the leakage of lubricating oil, coolant and other liquids inside the equipment, prevent the intrusion of external dust, impurities and other pollutants, ensure that all parts of the mechanical equipment operate stably in a good environment, and extend the service life of the equipment. In the hydraulic system, stable sealing is the key to ensuring the normal operation of the system. With its excellent sealing performance, silica gel O-ring seals can withstand the high pressure inside the system, prevent hydraulic oil leakage, and ensure the stable transmission of hydraulic power. In the pneumatic system, the sealing requirements for gas are equally strict. Silica gel O-ring seals can effectively seal the gas, ensure the stability of the pressure of the pneumatic system, and enable the pneumatic components to move accurately according to the design requirements. Silicone O-ring seals can form a reliable seal at the connection part of the pipe docking to prevent medium leakage.
Outstanding performance characteristics
Silica gel O-ring seals are made of ordinary silicone rubber with excellent high temperature resistance. It can maintain stable physical and chemical properties in high temperature environments. In high-temperature yarn dyeing cylinders, the internal temperature is often high. Silica gel O-ring seals can work continuously and stably in this environment to ensure that the dyeing liquid will not leak and ensure the smooth progress of the yarn dyeing process. Silica gel O-ring seals show good tolerance to various oils such as mineral oil, phosphate ester hydraulic oil, and chemical media such as strong acids and alkalis. Silica gel O-ring seals can effectively resist the erosion of these media and maintain the integrity of their own structure and performance. Silicone O-ring seals have high-strength resilience and can quickly return to their original shape when compressed by external force. This high resilience combined with good elasticity makes its sealing performance extremely excellent. In practical applications, it can effectively prevent water and leakage and has a long service life. In the field of electronic equipment, dust and water vapor are important factors affecting the performance and life of the equipment. Silica gel O-ring seals can effectively prevent dust and water vapor from entering the interior of the equipment, protect electronic components from contamination, and ensure the stable operation of electronic equipment in various complex environments. During the operation of mechanical equipment, vibration and noise will be generated. It can absorb and buffer the vibration energy generated by the operation of the equipment and reduce the friction and collision between the equipment parts. Silicone O-ring seals are highly versatile and suitable for both dynamic and static sealing conditions. In dynamic sealing scenarios, such as the sealing of rotating shafts, it can always maintain a close fit with the shaft surface during the operation of the equipment, effectively preventing medium leakage. In static sealing situations, such as the sealing of equipment flange connections, it can also perform excellent sealing performance.
