Terminal Polymer Filtration System for Continuous Polymerization Production Lines

The Final Polymerization Melt Filter is a high-temperature polymer filtration system specially designed for terminal filtration applications in continuous polymerization production lines.

Installed at the final stage of the polymerization process, the equipment performs high-precision melt filtration before downstream extrusion, spinning, pelletizing, or film production processes. It effectively removes gels, black spots, catalyst residues, metal particles, and polymer degradation impurities, ensuring stable polymer melt quality and continuous production operation.

Automatic Backwash Melt Filtration System for Polymer Extrusion Lines

The Backflush Screen Changer is an automatic melt filtration system for continuous melt filtration in extrusion and recycling applications. The Backflush Screen Changer uses the latest backflush cleaning technology. This allows the contaminants on the filter screen to be flushed off automatically during operation without any interruption to the process. The system removes all contaminants such as gels, degraded polymers, metal particles, black spots etc. from the melt. It maintains constant melt pressure and ensures continuous filtration. The Backflush Screen Changer is used in plastic recycling, pelletizing, sheet extrusion, film extrusion, pipe extrusion etc. applications, especially those with high output.

Hydraulic Continuous Melt Filtration System for Polymer Extrusion Lines

The Hydraulic Screen Changer is a high-performance melt filter for continuous use in extrusion and polymer processing. The easy and fast screen change, by hydraulic force, under high temperature and high pressure, is the main characteristic of this equipment. It removes contaminants, gels, black spots, degraded polymers and metal particles from molten polymers. The melt filter ensures constant extrusion pressure and excellent quality of the end product. Hydraulic Screen Changers are used in plastic recycling, pelletizing, sheet extrusion, film production, pipe extrusion, compounding and chemical fiber processing.

Polymer Melt Filtration System for Pre-Polymerization & Continuous Polymerization Production Lines

The Pre-Polymerization Melt Filter is a high-temperature polymer filtration syste

specially designed for pre-polymerization and continuous polymerization production processes.

Installed in the upstream stage of polymerization systems, the equipment performs preliminary melt filtration before the final polymer finishing stage, helping remove catalyst residues, gels, metal particles, degraded polymers, and process impurities from polymer melts.

The system adopts a large-area candle filtration structure and is designed for stable operation under high-temperature and high-pressure polymer processing conditions commonly found in PET, PA, PLA, and engineering polymer production lines.
