High-performance Metamax filter needle felt is a new high temperature resistant filter media with excellent performance. It takes 5.5 m glass fiber as the main raw material, mixed with high temperature fiber P84, Aramid 1313 (Metas), aramid 1414 Kevlar, PPS, PTFE, formed in three-dimensional porous structure with characterizes low operation resistance, especially P84 fiber cross-section showed irregular blade shape,increased by about 80% in the suface content, so it has strong resistance and dust catching ability, kinds of fiber materials blends together so that the polarity of the complementary filter can capture fine dust. At the same time P84 irregular cross-section of the fiber with involve entanglement force strong, greatly improve the peel strength between the substrate and the felt layer, so that the filtration velocity increased by 50%, can reach 1 ~ 1.4m/min, and the wear resistance is increased by 3 to 4 times, greatly improve the service life.

Application:

Metamax filter bags is suitable for high temperature flue gas filtration in steel, metallurgy, chemical industry, coal-fired boiler, incinerator, refractory and cement. It is suitable for dust collector baghouse filter with pulse-jet cleaning and high speed air blowing. After a long test of high temperature and corrosive medium, the filter material has excellent performance, and it can effectively control emission and recover valuable fine particles.
