PP Melt Blown Filter Cartridges are made of PP fibre manufactured by different pore diameter of spray nozzles depth construction with fine fibers in inner layer when in outer layer fiber is coarse It is high dirt holding capacity low pressure drop high flow rate good chemical resistance no fibre release longer service life and effectively filtration for suspended particle sediment Absolute melt blown filter cartridges was made of high performance pure polypropylene depth dual-gradient density filter media under highly controlled manufacturing process which request exceptional dirt-holding capability and the outstanding performance for critical filtration application It has the premium feature that filtering efficiency could come to 99 9% and guarantees consistently

Design of electret polypropylene melt blown air filtration

In summary we successfully designed a fluffy PP/MgSt electret melt blown filtration material with high filtration efficiency and low air resistance First a fluffy nonwoven filter with fine fiber diameter small pore size and high porosity was achieved by regulating the melt blown DCD Then by introducing a nucleating agent into the PP polymer during the melt blown process the electret

Melt‐blown polypropylene (PP) electret fabrics are widely used as air filter media due to the specific mechanism of electrostatic filtering In this article two additives stearate and modified rosin are doped to PP fabrics during melt‐blown process The filtration performance of doped PP gets improved greatly with filtration efficiency increased by 6% at room temperature but its
