AFLAS 90

AFLAS 90, a tetrafluoroethylene and propylene copolymer (FEPM), has a fluorine content up to 54%. This polymer has some excellent physical and chemical properties, temperature resistance, and more, which makes it suitable for sealing applications in industries with harsh environments, such as chemical, petroleum, oil & gas, and so on. It is black in color and withstands a wide temperature range. SSP Seals offers sealing products made using AFLAS 90 for diverse industries. Most commonly, we make gaskets and O-rings with AFLAS 90 which can be used for high-temperature applications and offers a high degree of reliability. 

Properties of AFLAS 90 Polymer

These properties of AFLAS 90 make it a reliable material for sealing applications. 

  • Chemical Properties: AFLAS 90 can resist chemicals, abrasive fluids, hydraulic fluids, aliphatic and aromatic hydrocarbons, alcohols, steam and hot water, oils & lubricants, acids and gases. Its chemical composition comprises tetrafluoroethylene + cured peroxide (propylene).
  • Physical Properties:This polymer is much harder than AFLAS 360, and has a good tensile strength. AFLAS 90 has almost all the physical properties of TFE/P. Also, its turnability is quite high. It has an elongation percentage of 133% and specific gravity is 1.6528. With this material, you can achieve tight tolerances for O-ring diameters and cross sections for other seal applications. Its shelf life without any changes is almost 10 years.
  • Temperature Resistance:AFLAS 90 has an excellent temperature resistance, and has an operating temperature range from -10 to 200 degrees Celsius. So, the heat resistance is excellent. Structurally, AFLAS 90 sustains till -40 degrees Celsius. However, it loses elasticity beyond -10. So, depending upon the application requirement, it can be used in low temperatures.
  • Flame Resistance:If it is exposed to fire or a flame, AFLAS 90 will burn. However, it would stop burning once the flame is removed.
  • Low Aromatizing properties:If you are looking for a rubber-like material without a strong aroma, for gaskets and seals applications, then AFLAS 90 is the right option. This is because of its low aroma.
