Oil-Gas Separator Substrate is a special functional material used for oil-water separation or oil-gas filtration. It is typically made from fibrous materials through special processes such as needle punching, melt-blowing, or weaving. It has hydrophobic and oleophilic properties or selective permeability, enabling it to effectively separate oil-water mixtures or filter impurities from oil-gas.
