Descriptions

 

PI FILLED PTFE CUPS SEALS APPLICATION

 
PI-filled PTFE cup seals are specialized seals that combine the benefits of polyimide and PTFE.
 
They are commonly used in:
 
 

Compressor Systems :

As piston cups in oil-free compressors, providing sealing solutions that minimize friction and wear, and prevent contamination.
 
 

Spring-Energized Seals :

They can be part of spring-energized U-cup designs, like FlexiSeal, for rod and shaft sealing in various hardware designs.
 
 

Rotary and Reciprocating Sealing :

Ideal for rotary and reciprocating movements due to their low friction and wear resistance against soft mating surfaces.
 
 

Stop-Start Applications :

Prevent stick-slip in systems with frequent starts and stops, ensuring smooth operation and component protection.
 
 

Cryogenic and High Temperature Environments :

Perform well in both low and high temperature extremes.
 
 

Vacuum and Low Outgassing Requirements :

Suitable for vacuum environments and applications where low outgassing is essential.
 
 

Abrasion Resistance :

Provide a balance between wear resistance and reduced abrasiveness, making them compatible with softer mating materials.
 
 
These seals can be customized to meet specific application requirements and are available in different shapes, sizes, and designs from various suppliers.

 

 

PTFE RAW MATERIAL PROPERTY

 

Polytetrafluoroethylene (PTFE), commonly known as Teflon, possesses several remarkable properties that make it suitable for various applications. Some of its key characteristics include:

 

  1. Chemical Resistance: PTFE is highly resistant to almost all chemicals, acids, bases, and solvents, making it ideal for use in harsh chemical environments.
  2.  
  3. Non-Stick Surface: Its low surface energy results in a slippery surface, preventing substances from adhering, which is beneficial in cookware and industrial applications.
  4.  
  5. High Temperature Resistance: With a high melting point around 327°C (620°F), it maintains stability and functionality at elevated temperatures.
  6.  
  7. Low Coefficient of Friction: PTFE has one of the lowest coefficients of friction, reducing wear and energy loss in sliding applications.
  8.  
  9. Dielectric Properties: It is an excellent electrical insulator, with high dielectric strength and a low dielectric constant.
  10.  
  11. Non-Toxic and Biocompatible: Safe for use in medical implants and food contact applications.
  12.  
  13. Low Thermal Conductivity: PTFE provides good thermal insulation due to its low thermal conductivity.
  14.  
  15. Lightweight and Strong: Despite its low density, PTFE is strong and durable, with good tensile strength and fatigue resistance.
  16.  
  17. Non-Flammable: PTFE is self-extinguishing and does not support combustion, making it fire-resistant.
  18.  
  19. UV Resistance: It is resistant to UV degradation, ensuring stability and performance in outdoor applications.
  20.  

PTFE raw material is available in different grades and forms, such as powders, pellets, and sheets, which can be modified with fillers like glass, carbon, or molybdenum disulfide to tailor its properties.
