PTFE O-rings

Chemically stable, high temperature resistant, protects your precision craftsmanship !

PTFE O-rings

Polytetrafluoroethylene (PTFE) O-rings are a type of seals made with PTFE material, which is known for its excellent chemical stability, high temperature resistance, low coefficient of friction, and non-stick properties. Below are some details of PTFE O-Rings:

 

What is the PTFE O-rings Material Properties ?

  • Chemical resistance: PTFE has excellent resistance to almost all chemicals, including strong acids, bases, organic solvents and oxidizers.
  • High Temperature Resistance: PTFE is able to maintain its performance in high temperature environments, typically ranging from -200°C to +260°
  • Low coefficient of friction: PTFE has an extremely low coefficient of friction, making it ideal for sliding seals.
  • Non-stick: PTFE has a non-stick surface and is not prone to adhering to substances.
  • Electrical insulation: PTFE has good electrical insulation properties and is suitable for sealing electrical and electronic equipment.
  • Aging resistance: PTFE has good anti-aging properties, can maintain its physical and chemical properties in long-term use.
  • Mechanical properties: PTFE has low tensile strength and modulus of elasticity, but its abrasion resistance and compression resistance are better.

 

Which are the PTFE O-rings Application field ?

PTFE O-rings are widely used in chemical, semiconductor, aerospace, medical equipment, food processing and other industries for sealing corrosive media, high-temperature environments or equipment and pipelines that require good electrical insulation properties.

 

How does the PTFE O-rings Manufacturing Process ?

PTFE O-Rings are typically manufactured through a molding or turning process. Molding is to put the pre-mixed PTFE powder into the mold and form it under high temperature and high pressure; turning is to process PTFE rods into the shape of O-ring through lathe.

 

What is the PTFE O-rings Specification and standard ?

PTFE 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: PTFE materials should be stored in a dry, cool, well-ventilated place, avoiding direct sunlight and high temperatures.
  • Use environment: Although PTFE is chemically resistant and high temperature resistant, 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 PTFE O-rings to ensure the sealing effect.The selection and use of PTFE O-rings need to be determined according to the specific application environment and requirements to ensure the best sealing effect and service life.
