Comparing Polyester and Polypropylene Filter Bags
Industry Applications of Polyester and Polypropylene
In this section, we will delve into the distinctions between polyester and polypropylene filter bags. Polyester is recognized as one of the most commonly used filter media within the dust collection sector due to its dependable performance across a range of applications. On the other hand, polypropylene offers a relatively economical alternative. A notable difference between the two is polypropylene's capacity to endure moisture. Should your operating temperatures stay between ambient and 170 degrees Fahrenheit, and moisture levels exceed 10%, then polypropylene may suit your needs.
