Detailed Introduction

P84 needle felt is made of P84 fiber (i.e. polyamide fiber) producedby Austrian LENZING company through three-dimensionalneedle punching, which has good high temperature resistance,temperature resistance up to 280° C, and P84 fiber cross-sectionis irregular leaf-like, which can greatly improve the filtration effect.The fiber itself also has a certain degree of hydrolysis resistance,oxidation resistance, the product has good temperature resistance,good filtration effect, and is widely used in concrete mixing,cement, garbage incineration, coal-fired boilers and other complexworking conditions.
