PPS Filter Bag

PPS filter bag (Polyphenylene Sulfide) is a high-performance high-temperature resistant filter material designed for harsh flue gas dust collection conditions. It is widely used in bag filters for coal-fired power plants, industrial boilers, waste incineration, metallurgy, cement and chemical industries.

With excellent thermal stability, chemical corrosion resistance and dimensional stability, PPS filter bags ensure high dust removal efficiency, low pressure loss and long service life under high-temperature and corrosive flue gas conditions.

Recommended Surface Treatment for PPS Filter Bags

Different dust properties require different surface treatments to ensure optimal filtration efficiency, cleaning performance and service life. The following guide helps you select the most suitable treatment for your application.

How to Read This Guide

Each row represents a typical dust property.

The blue highlighted column indicates the most effective surface treatment for that condition.

For example:

Free-flowing dust: Choose singed finish for easy cake release.

Humid or sticky dust: Hydrophobic/oleophobic treatment prevents moisture and oil from clogging the fabric.

Acidic/alkaline flue gas: PTFE impregnation enhances chemical resistance.

Ultrafine dust: Microfiber layer improves capture efficiency for fine particles.

We can provide filter bags with one or multiple combined treatments according to your specific working conditions.
