P84 acid and alkali resistant needle felt is INSPECFIBERS (polyimide fiber) produced by our company LENZING Company of Austria. It is a high-efficiency filter material with high temperature resistance and acid and alkali resistance developed by other non-woven fabric production process. At present, there are only a few manufacturers in China that independently develop, design and produce the filter material. P84 filter material has high temperature resistance (can be used for a long time below 260 °C) and good chemical resistance. It has a very significant filtering effect on dusty gas with acid and alkali, making it prominent in the waste incineration industry. Higher dust removal efficiency.
