Non Woven Filter Cloth for Industrial Dust Collection

Aramid needle felt is designed for higher-temperature dust collection. It is commonly used in asphalt mixing plants, cement processes, metal production and other systems where polyester cannot tolerate the operating temperature.

PTFE needle felt is selected for severe chemical exposure and high operating temperatures. The fiber resists most acids and alkalis and does not absorb moisture in the same way as many conventional materials.

PPS is widely used where heat, moisture and acidic gas occur together. It performs well in coal-fired boilers, power generation and selected chemical processes because it resists hydrolysis and many acids and alkalis.

P84 is a polyimide filter material recognized for its irregular, multilobal fiber shape. This creates a large fiber surface area and supports effective fine-dust capture without relying entirely on a heavy dust cake.

Acrylic needle felt is often considered when the gas is too wet or mildly acidic for conventional polyester but does not require a high-temperature material.

Polyester is the standard choice for many dry dust collection systems operating at moderate temperatures. It offers useful mechanical strength, stable dimensions and good resistance to normal baghouse cleaning cycles without pushing material cost unnecessarily high.
