fluoroelastomerit

Fluoroelastomer is a type of synthetic rubber that is known for its excellent resistance to heat, chemicals, and weathering. It is a copolymer of tetrafluoroethylene (TFE) and perfluoroalkyl vinyl ether (PFAVE), which gives it a unique combination of properties that make it suitable for a wide range of applications. The most common type of fluoroelastomer is Viton, which is a registered trademark of DuPont.

Fluoroelastomers are typically used in applications where exposure to extreme temperatures, harsh chemicals, or aggressive environments is expected. They are often used in seals, gaskets, and O-rings for industrial machinery, automotive components, and aerospace applications. Their resistance to compression set, which is the permanent deformation that occurs when a material is compressed and then released, makes them ideal for applications where repeated compression and decompression cycles are expected.

The chemical structure of fluoroelastomers gives them excellent resistance to a wide range of chemicals, including oils, fuels, and solvents. They are also resistant to ozone, UV radiation, and weathering, which makes them suitable for outdoor applications. However, they are not resistant to strong oxidizing agents, such as concentrated sulfuric acid or nitric acid.

Fluoroelastomers are typically processed using compression molding, extrusion, or injection molding techniques. They can be reinforced with fillers, such as carbon black or silica, to improve their mechanical properties. They are also available in a wide range of durometers, which is a measure of their hardness, to suit different applications.

In summary, fluoroelastomer is a versatile and durable synthetic rubber that is known for its excellent resistance to heat, chemicals, and weathering. Its unique combination of properties makes it suitable for a wide range of applications in industries such as automotive, aerospace, and industrial machinery.
