Product Introduction
Filter paper is suitable for filtering transformer oil, turbine oil, mechanical oil, and diesel; refining lubricants and filtering petroleum jelly in oil refineries; filtering for waste oil regeneration, insulating paint, dyes, beverages, and fine chemicals. The filter paper offers excellent filtration and absorption performance along with considerable compressive strength. It is suitable for filtering industrial organic suspended turbid liquids such as petroleum, chemical products, and industrial oils to separate solid and semi-solid impurities. For example, when used with filter presses, it can filter transformer oil, turbine oil, molten paraffin, synthetic resins, dioctyl sebacate, and various other organic liquids. Filter paper is not suitable for filtering aqueous or other inorganic liquid suspensions.
