P84 needle punched felt by Austria LENZING company production of P84 fiber (i.e. poly amide fibers) by three dimensional needled,has good resistance to high
temperature performance, heat resistance up to 280°C, and P84 fiber cross section is irregular leaflike,can greatly improve the filtering effect. Fiber itself and the
hydrolysis resistance, oxidation resistance, the resistance temperature of good,good filtering effect, widely applicable in concrtet stirring, cement, waste incineration,coal-
fired boilers and other complex conditions use.
