Feature of PTFE Filter Bags
- Excellent high temperature resistance: Withstands continuous operating temperatures up to 260°C (500°F) and can reach up to 300°C (572°F).
- Excellent acid and alkali resistance: PTFE can withstand almost all chemicals, making it an ideal material for filtering corrosive substances.
- High filtration efficiency: Low coefficient of friction helps prevent particles from sticking and effectively captures fine particles.
- Hydrophobicity: PTFE naturally repels water and other liquids, helping to control humidity in critical applications
- Durable: The service life can reach 6 years under normal operating conditions in the temperature range of 66°C to 204°C.
