Zusammenfassung:	PURPOSE:To provide a plastic filter for collecting and separating fine dust particles from a gaseous or liq. medium. CONSTITUTION:The mixture consisting of 90-50wt.% of a high-density PE powder having =2 kinds among polytetrafluoroethylenes, a tetrafluoroethylene-hexafluoropropylene copolymer and polyvinylidene fluoride are deposited in the pore on the surface of the substrate to obtain the filter. Consequently, the mechanical strength is increased, the pressure drop is reduced, the substrate is sintered at a low temp. in a short time, and the cost is reduced.
