PP (Polypropylene) agitators are industrial mixers for tanks, commonly available as Anchor, Propeller, Turbine, or Helical types, often lined with PP or HDPE for chemical resistance, used in industries like chemical processing, textiles, and food, with designs varying by fluid viscosity and mixing needs. Key types include Anchor for high viscosity, Propeller for general blending, Turbine for dispersion, and Helical for thick pastes.
