PTFE Filter Bags vs. Polyester Filter Bags: What's the Difference

If you're trying to decide between PTFE and polyester filter bags, it's important to consider the specific needs of your application.

PTFE (polytetrafluoroethylene) and polyester filter bags are two popular choices for industrial applications that require reliable air pollution control. While both types of bags are effective at capturing dust particles, they have some important differences that may make one a better choice than the other for your specific needs.

One key difference between PTFE filter bags and polyester filter bags is their resistance to high temperatures. PTFE filter bags can withstand much higher temperatures than polyester bags, making them a better choice for applications that involve high-temperature gases or steam.

Another difference is their resistance to chemicals and corrosive substances. PTFE filter bags are highly resistant to chemicals and can withstand exposure to a wide range of corrosive substances, making them a good choice for industries such as chemical processing and pharmaceuticals. Polyester filter bags are less resistant to chemicals, and may not be the best choice for applications involving corrosive gases.

When it comes to cost, polyester filter bags are generally less expensive than PTFE bags. However, PTFE bags may have a longer lifespan, making them a more cost-effective option over time.
