What are Perfluoroelastomers Made Of?
Perfluoroelastomers are composed of carbon, fluorine, and oxygen atoms. These materials are combined to create a polymer with a highly stable and inert structure. This unique combination results in a material that is resistant to a wide range of chemicals, including acids, bases, solvents, and fuels.
Structure and Properties of Perfluoroelastomers and Fuoroelastomers
Perfluoroelastomers belong to a family of elastomers called fluoroelastomers. The main difference between perfluoroelastomers and other types of fluoroelastomers is the absence of hydrogen atoms in their structure. This makes them highly resistant to degradation under harsh chemical and thermal conditions.
In addition, perfluoroelastomers have excellent mechanical properties, such as high tensile strength, elongation at break, and tear resistance. They also exhibit a low compression set, meaning they can maintain their original shape after being compressed for long periods.
Who Discovered Perfluoroelastomer and When was it Patented?
Perfluoroelastomers were first discovered in the 1960s by a team of researchers at DuPont, who were experimenting with different types of fluorinated polymers. The team was led by Dr. William Gore, and their work resulted in the creation of Viton®, one of the most well-known trade names for perfluoroelastomers.
In 1965, DuPont patented perfluoroelastomers under the brand name Kalrez®. Since then, other companies have also developed and patented their own versions of perfluoroelastomers, such as Chemraz® by Greene Tweed and Perlast® by Precision Polymer Engineering.
Chemical Resistance
One of the main reasons why perfluoroelastomers are widely used is their exceptional chemical resistance. They can withstand exposure to harsh chemicals without degrading or losing their properties. This makes them ideal for use in industries where corrosion and chemical reactions are a concern. In addition, perfluoroelastomers are also resistant to high levels of radiation, making them suitable for use in nuclear power plants.
Temperature Resistance
Perfluoroelastomers have the ability to withstand extreme temperatures ranging from -26°C to 325°C (-15°F to 617°F). This makes them ideal for use in applications where exposure to both hot and cold environments is common. They can maintain their elasticity and mechanical properties even at high temperatures, which is crucial for industries such as aerospace and automotive.
Applications of Perfluoroelastomers
With their exceptional chemical and temperature resistance, perfluoroelastomers have a wide range of applications in different industries. Some common uses include:
- O-rings and seals: Perfluoroelastomers are commonly used to make o-rings and seals due to their ability to resist extreme temperatures and harsh chemicals.
- Gaskets: They are also used in gaskets for applications that require high levels of chemical resistance and temperature stability.
- Semiconductor industry: In the semiconductor industry, perfluoroelastomers are used in critical components such as wafer carriers, valves, and fittings due to their ability to withstand corrosive chemicals and high temperatures.
- Aerospace industry: Perfluoroelastomers are used in aircraft engines and other critical components due to their resistance to jet fuel, hydraulic fluids, and extreme temperatures.
- Automotive industry: They are also used in automotive applications such as seals, gaskets, and hoses for their ability to withstand exposure to fuels, oils, and high temperatures.
