PP Filter Mesh, also known as Polypropylene Filter Mesh, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles, stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes. Polypropylene is stiff, not like polyester filter mesh and nylon filter mesh. Due to good chemical resistance, PP filter mesh is widely applied in environments of strong acid and alkali.
