Silicone seals and rubber seals are common sealing materials, and they have their own advantages in different application environments and requirements. Which kind of sealing ring should be selected according to the specific conditions of use and requirements. Here are some comparisons of the two:

silicone sealing ring:

High temperature resistance: Silicone sealing ring has good high temperature resistance and can maintain elasticity and sealing at higher temperatures.

Chemical resistance: Silica gel has good resistance to some chemicals and is not susceptible to corrosion.

Oxidation stability: Silica gel remains stable for a long time and is not easy to oxidize.

Insulation performance: Silicone is an excellent insulating material, suitable for electrical equipment.

Wide range of hardness: Silicone sealing rings of different hardness can be made to adapt to different application scenarios.

rubber sealing ring:

Wear resistance: rubber sealing ring has good wear resistance, suitable for some mechanical seal occasions.

Elasticity: The rubber sealing ring has good elasticity and can provide effective sealing performance under relatively low pressure.

Low cost: Under normal circumstances, the manufacturing cost of rubber sealing ring is relatively low.

Selective: There are many types of rubber seals, such as nitrile rubber, fluorine rubber, etc., and suitable materials can be selected according to different needs.

When choosing a sealing ring, it is necessary to consider factors such as the temperature, pressure, and chemical substances of the use environment, as well as the elasticity and durability of the sealing requirements. Taking these factors into account, it is better to determine whether to use a silicone seal or a rubber seal.
