ePTFE membrane for dust collector filter bags
Huzhou Kaili New Material Technology Co., Ltd. produces premium ePTFE (expanded Polytetrafluoroethylene) membranes specifically engineered for the high-performance filtration market. When laminated to filter media, our ePTFE membrane transforms a standard filter bag into a high-efficiency surface filtration tool capable of capturing sub-micron dust particles while maintaining low operational pressure.
As a core manufacturer in the Kaili Advanced Materials Group, we specialize in the custom finishing and lamination of these membranes to various industrial substrates like Polyester, PPS, Aramid, and Fiberglass.
