Folding pleated mesh polymer melt filter is specially used to remove gel, carbonized particles and impurities in molten polymer. It is widely used in chemical fiber, plastic and textile industries. It adopts stainless steel pleated filter element or pleated filter disc structure, and guarantees the purity and quality of high-performance fiber, film and resin products by increasing the filtration area and multi-layer depth filtration.
