P84 fiber has irregular shape section like leaves, therefore, it has about 80% more surface area than that of the fibers with regular round round section. That ensures the high efficiency of filtration and prevents the dust to infiltrate deeply into the filtration material. The material can be used under the temperature of 240℃ (long-term) and 260℃(short-term), suitable to be used with PH5-9, It is on of the few materials that can stand such high temperature. The fiber has good hydrolysis stability, LOI(limit oxygen index) of it is 38%.The filtration bag is suitable for long  time working with high amount of dust and chemical load conditions. The filtration materials is the best choice for the dust collection in the industry environment of outlet of cement kiln and waste incineration.
