Silicone sealing ring is mainly used in some electronic equipment and mechanical equipment, its size is divided into different proportions, and in the process of use, it may be due to extrusion or friction and other factors, resulting in a decline in service life. The main factors causing wear of silicone sealing ring in the process of use depend on which aspects?

In addition to damage, the wear degree of a silicone product mainly depends on the strength of use, that is, the friction pressure. The wear rate of the silicone seal has a certain correlation with the working pre compression. When the sealing ring works normally, the liquid is under pressure, In Matcha, with the increase of working pressure, the friction becomes greater!

When the working pressure is less than 20MPa, it is approximately linear. When the pressure is greater than 20MPa, with the increase of pressure, which friction has an impact on the application of O-ring? Gradually slow, the increase of friction is also slow. Under normal conditions, the service life of O-ring will decrease approximately in a square relationship with the increase of liquid pressure. With the increase of friction, a lot of friction heat is generated between the rotating or reciprocating shaft and the O-ring.

Because most O-rings are made of silica gel and rubber, the thermal conductivity of rubber O-rings is very poor. Therefore, the friction heat will cause the aging of rubber, leading to the failure of O-ring and its sealing performance. Friction can also cause the surface damage of O-ring and reduce the compression. Serious friction will quickly cause the surface damage of O-ring and lose its sealing property.

Therefore, the friction of silicone O-ring has a great influence on the service life of O-ring to a great extent, so do not ignore its friction when applying O-ring.
