High Sealing Performance Silicone O Ring Fluorine Rubber Seals

  When it comes to seals, two popular options are silicone seals and fluorine
rubber seals. Both have their unique characteristics and advantages. In this
article, we will compare the two and determine which one is better based on
their properties, applications, and performance.

  1. Properties:

  Silicone seals are made from a synthetic rubber known as silicone. They
have excellent resistance to high and low temperatures, as well as good
flexibility and durability. Silicone seals also have good resistance to
chemicals, UV rays, and ozone. On the other hand, fluorine rubber seals are
made from a material called fluorocarbon elastomer. They have exceptional
chemical resistance, especially to oils, fuels, and solvents. Fluorine rubber
seals also have high thermal stability and low gas permeability.

  2. Applications:

  Silicone seals are commonly used in a wide range of industries, including
automotive, aerospace, and industrial machinery. They are often used in sealing
applications where temperature fluctuations are expected, such as engine seals
and hydraulic seals. Silicone seals are also suitable for food-grade
applications due to their non-toxic and odorless properties. On the other hand,
fluorine rubber seals are preferred in industries where resistance to
aggressive chemicals and oils is crucial, such as chemical processing, oil and
gas, and automotive. They are commonly used in sealing applications that
require resistance to corrosive fluids and high temperatures.

  3. Performance:

  In terms of performance, both silicone seals and fluorine rubber seals
offer excellent sealing capabilities. However, silicone seals have an advantage
when it comes to temperature resistance. They can withstand a wider range of
temperatures, from extremely low to extremely high, without losing their
sealing properties. Fluorine rubber seals, on the other hand, excel in chemical
resistance. They can withstand exposure to oils, fuels, and solvents without
deteriorating or swelling. Additionally, fluorine rubber seals have better
resistance to aggressive chemicals, making them suitable for demanding sealing

  Both silicone seals and fluorine rubber seals have their own strengths and
applications. If you require an oil seal with excellent resistance to high and
low temperatures, good flexibility, and durability, silicone seals are the
better choice. On the other hand, if you need an oil seal with exceptional
chemical resistance and high thermal stability, fluorine rubber seals are the
preferred option. Additionally, silicone seals are more versatile and can be
used in various industries, while fluorine rubber seals are specifically
designed for applications involving aggressive chemicals and oils. So, the
choice between silicone seals and fluorine rubber seals depends on the specific
requirements of your sealing application.
