Material Structures
Engineered ePTFE microstructure for pressure control, chemical resistance and long-term sealing performance.
Why Material Structure Matters
Pressure Stability
Prevents container deformation
Leak Protection
Blocks liquid penetration
Long-Term Reliability
Stable in harsh environments
ePTFE Node–Fibril Structure
The membrane is built on a microporous node–fibril network formed by controlled stretching and sintering of PTFE.
This structure creates airflow channels while maintaining a strong liquid barrier.
