In addition to being hydrophobic, which means it repels water, PTFE is known for its chemical resistance, non-stickiness, high-temperature tolerance, and low friction coefficient. These properties make PTFE filter bags ideal for a wide range of filtration applications.
- High Filtration Efficiency
-
- Chemically Inert
-
- Excellent Thermal Stability
-
- Low Friction Coefficient
-
- Excellent Hydrolysis Resistance
-
- Excellent Oxidation Resistance

In addition to these filtration characteristics, PTFE filter bags also offer a number of other advantages, such as:
- Long Service Life - PTFE filter bags have a long service life, even in challenging operating conditions. This can lead to significant cost savings over time.
- Easy to Clean and Maintain - PTFE filter bags are easy to clean and maintain, which helps to reduce downtime and improve productivity.
- Lower Energy Consumption - Because of Teflon filter bags' enhanced cleaning efficiency, it helps to reduce the overall pressure drop across the filter media, improving the efficiency and energy consumption of the dust collection system.
