Product Description

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.
