Automotive rubber sealing rings, also known as silicone rubber O-rings, belong to a category of silicone products. Its scope of application means it is used for sealing and waterproofing.
The temperature adaptability of automotive rubber sealing rings is strong, and they can be used at temperatures ranging from -50 ℃ to 250 ℃. They are basically permanently used at 150 ℃ without any performance changes, and their unique materials can meet the standard of 300 ℃. Therefore, even boiling water is not easily harmful to automotive rubber seals. If the food product needs to be sealed, silicone sealing rings can also be used because silicone products are non-toxic, odorless, and have a professional level qualification certification system, such as food grade silicone, medical grade silicone rubber, etc.
Automotive rubber sealing rings also have good insulation performance, with their dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistance coefficient, and surface resistance coefficient ranking second among insulation materials. Moreover, their electrical performance is particularly affected by temperature and frequency.
Therefore, the waterproof performance of the car rubber sealing ring is very good. And different types of sealing rings can be produced based on different sealed objects, such as fluororubber sealing rings, chloroprene rubber sealing rings, nitrile rubber sealing rings, etc.
