It is primarily used to separate different types of plastics in mixed plastic materials for effective recycling and reuse.

Recycled plastics are typically composed of various types, colors, and shapes of plastics. Examples include polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polyoxymethylene (POM), polyamide (commonly known as nylon) (PA), polycarbonate (PC), and acrylonitrile butadiene styrene (ABS), among others. These plastics have different chemical properties and electrostatic characteristics. The electrostatic separator utilizes the principles of static electricity to separate different types of plastics. When plastics are subjected to electrostatic charges, they acquire different charges. By attracting or repelling the charged plastics, different types of plastics can be separated. This efficient sorting capability significantly improves the quality and value of recycled plastics, as the separated plastics often command higher prices in the market.
