Product introduction
PTFE membrane has strong hydrophobicity and the ability to repel water-based fluids (hydrophobicity), which can protect equipment from external water vapor, volatile organic compounds, acid gases, etc., and is suitable for microelectronics and semiconductor industries.
Product features and advantages
1. Strong hydrophobicity, high mechanical strength
2. High flow rate
3. Long sterilization life and cost reduction
4. Chemical resistance, high temperature resistance
5. Anti-penetration in humid environment
6. Prevent short circuit
