Silicone sealing rings and rubber sealing rings are common sealing materials, and they have their own advantages under different application environments and needs. Which sealing ring to choose depends on the specific conditions and requirements of use. Here are some comparisons between them:
Silicone sealing ring:
High temperature resistance: The silicone sealing ring has good high temperature resistance and can maintain elasticity and sealing at higher temperatures.
Chemical resistance: Silicone has good tolerance to some chemicals and is not susceptible to corrosion.
Oxidation stability: Silicone remains stable for a long time and is not prone to oxidation.
Insulation properties: Silicone is an excellent insulation material suitable for electrical equipment.
Wide hardness range: Silicone seal rings of different hardness can be made to adapt to different application scenarios.
Rubber sealing ring:
Wear resistance: Rubber seals have good wear resistance and are suitable for some mechanical seals.
Elasticity: The rubber sealing ring has good elasticity and can provide effective sealing performance under relatively low pressures.
Lower cost: Usually, the manufacturing cost of rubber seals is relatively low.
Strong selectivity: There are many types of rubber seals, such as nitrile rubber, fluorine rubber, etc., and the right material can be selected according to different needs.
When selecting the sealing ring, factors such as the temperature of the environment, pressure, the influence of chemicals, and the elasticity and durability required by the seal need to be considered. Considering these factors, it is better to determine whether to use a silicone seal ring or a rubber seal ring.
