Characteristics, Advantages and Applications of Special PTFE Materials in Tank Containers

Polytetrafluoroethylene (PTFE), commonly known as the "King of Plastics," is a polymer material with excellent chemical stability and temperature resistance. With the advancement of industrial technology, ordinary PTFE can no longer meet all application requirements, leading to the development of various specialized PTFE materials, such as modified PTFE and expanded PTFE.

01. Modified PTFE Material

• Modified PTFE gasket

 

• PTFE Gasket With Carbon Fiber

 

• Polyphenylene Ester Containing PTFE

• PTFE Gasket with Blue Glass Fiber

• PTFE Gasket with White Glass Fiber

Modified PTFE is a series of materials created by adding various fillers or chemically modifying PTFE:

1. Glass fiber-reinforced PTFE: Adding glass fiber improves mechanical strength and wear resistance.
2. Graphite-filled PTFE: Improves thermal conductivity and dimensional stability.
3. Carbon fiber-reinforced PTFE: Significantly improves mechanical strength and wear resistance.
4. Bronze-filled PTFE: Enhances thermal conductivity and compressive strength.

02. Expanded PTFE（ePTFE）

• Expanded PTFE Gasket

• Extruded PTFE Manlid Gasket

Expanded PTFE is a new type of material that forms a microporous structure by expanding PTFE through a special process.

03. PTFE spiral wound gasket

A PTFE spiral wound gasket is a composite sealing gasket made by spirally winding polytetrafluoroethylene (PTFE) strips with metal strips (such as stainless steel or titanium alloy). Combining the excellent chemical resistance of PTFE with the high strength of a metal core, it is widely used for flange sealing in high-pressure, high-temperature, and highly corrosive environments.
