Perfluorinated rubber, also known as fluororubber, is a special synthetic rubber made from fluorine-containing polymers. Due to its excellent high temperature resistance, corrosion resistance, oil resistance and excellent insulation properties, perfluorinated rubber is widely used in many demanding fields, such as aerospace, petrochemical, automotive manufacturing, etc. In this paper, the properties, preparation and application of perfluorinated rubber are introduced in detail.
First, the performance of perfluorinated rubber
1. High temperature resistance: Perfluorinated rubber has excellent high temperature resistance and can work stably in extreme high temperature environments for a long time. Its long-term use temperature can reach more than 200 ° C, and even in an environment of about 300 ° C for a short time, no significant thermal degradation will occur.
2. Corrosion resistance: Perfluorinated rubber has very high corrosion resistance to most chemicals, including strong acids, strong alkalis, oxidants, etc. This makes perfluorinated rubber an ideal material in highly corrosive environments.
3. Oil resistance: Perfluorinated rubber has excellent permeability resistance to various oils, solvents and fuels, and can maintain long-term stable performance.
4. Electrical insulation performance: Perfluorinated rubber has high electrical insulation performance and can be used to manufacture high voltage insulation materials.
5. Mechanical properties: Perfluorinated rubber has excellent elasticity, strength and wear resistance, and can maintain good mechanical properties in a variety of complex environments.
Second, the preparation of perfluorinated rubber
The preparation of perfluorinated rubber is mainly by polymer synthesis. Commonly used polymer monomers include tetrafluoroethylene, vinylidene fluoride, trifluorochloroethylene and other fluorinated monomers. These monomers can be polymerized into linear or cross-linked polymers by emulsion polymerization, suspension polymerization or solution polymerization. Finally, after processing, perfluorinated rubber products of various shapes and specifications are prepared.
Third, the application of perfluorinated rubber
Due to its excellent properties, perfluorinated rubber has a wide range of applications. Here are some of the main application areas:
Aerospace: Perfluorinated rubber is widely used in the aerospace industry, such as aircraft seals, fuel tank sealing materials, etc., to cope with extreme temperatures and corrosive environments.
Petrochemical: In the petrochemical industry, perfluorinated rubber is used to manufacture pipe seals, valve seals, anti-corrosion linings, etc., to resist the erosion of various chemical substances.
1. Automobile manufacturing: Perfluorinated rubber is mainly used in automobile manufacturing to manufacture engine seals, fuel tank sealing materials and gas cylinder pressure seals, etc., to improve the durability and safety of automobiles.
2. High voltage piezoelectric insulation: Because perfluorinated rubber has high electrical insulation performance, it is also widely used in the field of high voltage piezoelectric insulation, such as high voltage cable insulation layer and transformer coil insulation material.
3. Biomedicine: Because of its physiological inertia and good biocompatibility, perfluorinated rubber is also widely used in the medical field, such as the manufacture of medical devices such as catheters and cardiac pacemakers.
Fourth. Summary
As a kind of high performance synthetic rubber, perfluorinated rubber is widely used in aerospace, petrochemical, automobile manufacturing and other fields because of its excellent high temperature resistance, corrosion resistance, oil resistance and electrical insulation properties. With the continuous progress of science and technology and the expansion of application fields, perfluorinated rubber will still play an important role in the future. An in-depth understanding of the properties, preparation and application of perfluorinated rubber helps to better leverage its advantages and promote the development of related industries.
