Specification :

High-temperature synthetic fiber needled felt filter material
The high-temperature synthetic fiber needled felt is made with a certain amount of synthetic fiber blended into the felt. Synthetic fiber includes P84, PPS, Kermal and PTFE. They have stronger interlocking capability. Compared with pure glass fiber needled felt, the peeling strength between felt and base fabric and friction resistance has increased 3 or 4 folds. Thus its service life is strikingly prolonged. It is mainly used for dust separation of coal-fired boiler and precious metal recovery in non-ferrous metallurgy.

Compound fiberglass needled felt filter material

The compound glass fiber is made with a certain amount of PPS or P84 fiber blended into the felt. PPS or P84 fiber has stronger interlocking capability. Compared with pure glass fiber needled felt, the peeling strength between felt and base fabric and friction resistance has increased 3 or 4 folds. Thus its service life is strikingly prolonged.
      The compound fiber needled felt is made from P84, PPS, Kermel and Metamax. It is mainly used for dust separation of coal-fired boiler and precious metal recovery in non-ferrous metallurgy. It is mainly used for cement and carbon black industries
