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.
