Fluororubber, a synthetic rubber that replaces some or all hydrogen atoms with fluorine atoms, stands out among many rubber materials due to its unique chemical structure and physical properties, showing many significant advantages. These advantages make fluororubber occupy an irreplaceable position in many high-end application fields.Fluororubber has excellent high temperature resistance. The fluorine-carbon bond energy in its molecular structure is extremely high, which enables fluororubber to maintain excellent elasticity and mechanical strength over a wide temperature range. Generally speaking, the operating temperature range of fluororubber can be from -20℃ to +250℃, and some specially formulated fluororubber can even be used for a short time at higher temperatures. This feature makes fluororubber particularly outstanding in high temperature environments. For example, in the fields of aerospace, automotive industry, etc., fluororubber is often used as key components such as seals and O-rings to ensure that the equipment can still operate stably under high temperature conditions.Fluororubber's chemical corrosion resistance is also one of its significant advantages. The high stability of the fluorine-carbon bond gives fluororubber excellent resistance to most chemicals and solvents, including strong acids, strong alkalis, organic solvents, etc. This allows fluororubber to maintain stable performance for a long time in environments such as the chemical industry and petroleum refining, and is not easily corroded or damaged.In addition, fluororubber also has good vacuum resistance and radiation resistance. In a vacuum environment, the gas permeability of fluororubber is extremely low, which can effectively prevent gas leakage and ensure the sealing of the equipment. At the same time, fluororubber is also highly resistant to radiation and can maintain stable performance in situations where medium radiation doses are applied, which is of great significance in fields such as the atomic energy industry.The mechanical properties of fluororubber are also excellent. It has high tensile strength and elongation at break, as well as good wear resistance and tear resistance. These characteristics give fluororubber unique advantages in the manufacture of seals, friction materials, etc., which can effectively reduce friction and wear and increase the service life of products.It is worth mentioning that fluororubber also has good electrical insulation properties. Although its electrical performance may decline in high-frequency and high-voltage situations, the electrical insulation performance of fluororubber is still reliable in low-frequency and low-voltage situations and can meet the needs of most electrical applications.In summary, fluororubber is unique among many rubber materials with its outstanding advantages such as excellent high temperature resistance, chemical corrosion resistance, vacuum resistance, radiation resistance, mechanical properties and electrical insulation properties. These advantages make fluororubber widely used in aerospace, automotive industry, chemical industry, petroleum refining, food processing equipment, and electronic and electrical fields, becoming one of the key materials to promote the development of related industries.
