General Description
We use the good imported P84 fiber to produce 100% Pure P84 needle felt fabric and P84 filter bag.As it's good performance of easy deashing, decay resistance, it is wide used in the cement plants, waste incinerators, fluid bed boiler coal fired boiler which industry have the higher request of the filter fineness and long using life. To meet the difference working condition, the P84（polyimide) fabric surface treatment can have done various processing such as water and oil repellent, PTFE impregnation and memberane.
Known as P84, Polyimide can be operated up to 230 under dry condition with good chemical
and thermal resistance although PTFE fiber exceeds these characteristics
It is weak with NO2 and hydrolysis in hot and wet conditions.
The P84 felt offers extended life using in low PH application and against acide attacks , resistant to flex abrasion
