AFLAS is a unique fluoroelastomer material developed by Asahi Glass Japan.AFLAS is a copolymer of tetrafluoroethylene (TFE) and propylene that combines the chemical resistance of fluoroelastomers with the low-temperature resistance of silicone rubbers, resulting in unique advantages in certain applications. Below are some details about AFLAS O-rings:

What is the Alfas O-rings Material Properties ?

• Chemical resistance: AFLAS has excellent resistance to a wide range of chemicals, including strong acids, bases, organic solvents and oxidizing agents.
• High Temperature Resistance: AFLAS is able to maintain its performance in high temperature environments, typically ranging from -40°C to +200°C, with some specially formulated AFLAS able to withstand higher temperatures.
• Low Temperature Resistance: AFLAS has excellent low temperature resistance and maintains flexibility at very low temperatures.
• Oil Resistance: AFLAS has good resistance to petroleum-based oils, lubricants and fuel oils.
• Mechanical properties: AFLAS has good elasticity and resistance to permanent deformation in compression, as well as good abrasion and tear resistance.

Which is the Aflas O-rings Field of application ?

AFLAS O-rings are widely used in the chemical, semiconductor, aerospace, automotive, oil and gas industries for sealing corrosive media, high-temperature environments, or equipment and piping that require good oil resistance.

How is the Afals O-rings Manufacturing Process ?

AFLAS O-Rings are typically manufactured through a molding or extrusion process. Molding is to put the pre-mixed AFLAS rubber material into the mold and form it under high temperature and high pressure; extrusion is to extrude the AFLAS rubber material into the shape of O-Ring through the extruder and then vulcanize it.

What is the Aflas O-rings Specifications and Standards ?

AFLAS O-Rings are available in a variety of sizes and hardnesses that can be customized for different applications. Common standards include ISO 3601 (international standard), AS 568 (American Standard), etc.

What should we pay attention to ?

• Storage conditions: AFLAS rubber materials should be stored in a dry, cool, well-ventilated place, avoiding direct sunlight and high temperatures.
• Use environment: Although AFLAS has good chemical resistance and high temperature resistance, it may still be affected under certain extreme conditions, such as a strong oxidizer environment at high temperatures.
• Installation Requirements: Avoid scratching or twisting when installing AFLAS O-rings to ensure sealing effectiveness.
• The selection and use of AFLAS O-Rings needs to be determined according to the specific application environment and requirements to ensure the best sealing effect and service life.
