What Materials Are Used for Dust Collector Filter Bags?

Dust collector filter bags are made from a variety of synthetic and fiberglass materials,each designed to handle specific temperatures,chemicals,abrasion,and dust types.Below are the most common filter bag materials used in industrial baghouses.

1.Polyester(PET)

The most widely used and cost-effective filter media.

Temperature range:≤130°C(266°F)

Good abrasion and acid resistance

Suitable for general industry:woodworking,cement,mining,feed,grain

2.Polypropylene(PP)

Excellent for corrosive and moist environments.

Temperature range:≤90°C(194°F)

Strong acid and alkali resistance

Ideal for chemical,fertilizer,and wastewater treatment industries

3.PPS(Polyphenylene Sulfide)

High-temperature and chemical-resistant media.

Temperature range:≤190°C(374°F)

Good hydrolysis resistance

Widely used for coal-fired boilers,waste incineration,and power plants

4.Aramid(Nomex/Conex)

Heat-resistant and high-strength material.

Temperature range:≤200°C(392°F)

Excellent abrasion resistance

Used in asphalt,steel,metallurgy,and cement kilns

5.PTFE(Teflon/Polytetrafluoroethylene)

Premium corrosion and high-temperature material.

Temperature range:≤260°C(500°F)

Extremely resistant to acids,alkalis,and chemicals

Used in harsh chemical plants,incinerators,and high-corrosion industries

6.Fiberglass(Glass Fiber)

Low-cost high-temperature media.

Temperature range:≤280°C(536°F)

Good dimensional stability

Mainly used in boilers,furnaces,and high-temperature flue gas treatment

7.P84(Polyimide)

High-efficiency,high-temperature filter media.

Temperature range:≤240°C(464°F)

Excellent fine dust capture

Used in waste incineration,carbon black,and high-temperature processes
