The compound glass fiber is made with a certain amount of PPS or Kermal fiber blended into the felt. PPS or Kermal 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 Kermal, 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 Features of Compound glass fiber needled felt
