high temperature, corrosion and wear.
The main features of PPS filter bags are as follows:
High heat resistance: The melting point of PPS filter bag is up to 285 ° C, the

thermal decomposition temperature is 490 ° C, and it can be used for a long

time in the temperature range of -190 ° C 260 ° C. This makes PPS filter bags

have a good application prospect under high temperature conditions, such as

coal-fired boilers, steel furnaces and so on.
2. Corrosion resistance: PPS filter bag has good corrosion resistance to most

chemicals and solvents, including acids, alkalis, oxidants and so on. This makes

PPS filter bags have a wide range of applications in chemical, petroleum and

other industries.
3. Good mechanical strength: PPS filter bag has high tensile strength, compressive

strength and impact strength, and can withstand large loads and impact forces.

This makes PPS filter bags have good stability under conditions such as

high-speed motion and vibration.
4. Size stability: PPS filter bag size stability is good, even under high temperature

and humidity conditions, the size change is small. This allows the PPS filter bag to

maintain better filtration energy during long-term use.
