Expanded eptfe gasket material 1mm~8mm

Expanded ptfe gasket material, also known as eptfe gasket material, is a highly versatile sealing product manufactured from expanded polytetrafluoroethylene (ePTFE) through a unique expansion process. This results in a soft, compressible material with a multidirectional fibrous structure that excels in sealing applications where traditional materials fall short. Unlike virgin PTFE, this expanded version offers enhanced conformability to uneven surfaces, superior recovery after compression, and excellent resistance to creep and cold flow, making it ideal for dynamic or high-stress sealing environments.

 Key Properties 

1. 1. Exceptional chemical inertness to acids, bases, solvents, and corrosive media
2. 2. Wide temperature range for continuous use in extreme conditions
3. 3. High compressibility and flexibility for reliable sealing on irregular flanges
4. 4. Low friction and non-stick surface
5. 5. Minimal creep and excellent bolt load retention
6. 6. FDA-compliant grades available for food, pharmaceutical, and potable water applications
7. 7. Easy to handle, cut, and install without specialized tools
