Perfluoroelastomer (PFE) is a high performance elastic material that has been widely used in many fields for its excellent properties. The following are the main characteristics and properties of perfluorinated rubber:
1. Chemical corrosion resistance
Excellent corrosion resistance: Perfluorinated rubber can maintain stability in extreme chemical environments and can resist high concentrations of acids, bases, organic solvents and oxidants.
Extensive chemical compatibility: suitable for the treatment of various corrosive chemicals, such as sulfuric acid, nitric acid, hydrofluoric acid, etc.
2. High temperature resistance
Excellent high temperature resistance: Perfluorinated rubber can maintain its physical and chemical properties in high temperature environments, and can usually work in the temperature range of -20°C to 200°C, and some special formulations can even be used for a long time at a temperature of 260°C.
Low temperature resistance: Perfluorinated rubber also has good low temperature resistance and can maintain its flexibility at extremely low temperatures.
3. Electrical insulation performance
Good electrical insulation: Perfluorinated rubber has excellent electrical insulation properties and is suitable for applications requiring high insulation requirements.
4. Mechanical properties
High tensile strength: Perfluorinated rubber has high tensile strength and tear resistance.
Good elasticity: Even under extreme conditions, perfluorinated rubber can maintain good elasticity.
Wear resistance: Perfluorinated rubber has excellent wear resistance and is suitable for applications requiring high wear resistance.
5. Weather resistance and aging resistance
Excellent weather resistance: Perfluorinated rubber can resist the effects of ultraviolet light, ozone and climate change, suitable for outdoor and long-term exposure to the natural environment applications.
Good aging resistance: Perfluorinated rubber is not easy to age and has a long service life.
6. Radiation resistance
Good radiation resistance: Perfluorinated rubber has good resistance to radiation and is suitable for high radiation environments such as the nuclear industry and medical equipment.
7. Low permeability
Low gas and liquid permeability: Perfluorinated rubber has extremely low gas and liquid permeability and is suitable for applications with high sealing requirements.
8. Biocompatibility
Good biocompatibility: Perfluorinated rubber performs well in medical devices and biotechnology applications and meets biocompatibility standards.
Sum up
Because of its excellent chemical resistance, high temperature resistance, electrical insulation, mechanical properties, weather resistance and aging resistance, radiation resistance, low permeability and biocompatibility, perfluorinated rubber is widely used in aerospace, automotive, chemical, electronics, medical equipment and other fields, is the ideal material for high-performance seals, gaskets, hoses and other key components.
