Sintered metal polymer filter tube for high-pressure extrusion melt filtration

Sintered Metal Polymer Filters

The Sintered Metal Polymer Filter utilizes a rigid, heavy-duty powder matrix for high-pressure depth filtration and gel trapping in polymer extrusion lines.

  • High Crush Resistance: Withstands extreme head pressures and $\Delta P$ without deformation or media migration.

  • Tortuous-Path Trapping: Interconnected micro-pores capture deformable gels and carbonized specks that bypass wire screens.

  • Thermal Cleanability: Reusable design fully compatible with vacuum pyrolysis or chemical stripping for extended service life.

  • Drop-In Fit: Available in customizable tubes or discs engineered for seamless industrial OEM replacement.

Sintered Metal Polymer Filters: High-Pressure Melt Filtration Elements

CMI Sintered Metal Powder Polymer Filters are high-strength, thick-walled porous metal filtration components specifically engineered for demanding polymer melt processing applications.

Manufactured from precision-sintered industrial metal powders, these elements form a rigid and highly controlled porous structure capable of capturing gel particles, degraded resin clusters, and carbonized contaminants under extreme extrusion pressures.

Unlike conventional mesh or fiber media, sintered powder filters provide stable filtration performance, exceptional mechanical strength, and reliable protection for downstream extrusion dies, gear pumps, and pelletizing systems.

Technical Specifications & Configurations

Media Type Sintered metal powder matrix (spherical or irregular powder particles)
Available Materials 316L Stainless Steel, Hastelloy® C-22, Inconel®, Pure Nickel
Filter Configurations Sintered powder discs, solid porous tubes, and thick-walled cylindrical elements
Structural Integrity High collapse pressure resistance designed for high-viscosity polymer melts

Key Performance Advantages

Exceptional Crush Resistance

Rigid sintered powder structures maintain precise pore geometry under high differential pressure without collapse or deformation.

Tortuous Path Filtration

Complex interconnected pore networks effectively capture deformable gels and contaminants that may pass through conventional wire mesh.

Zero Media Migration

Eliminates risks associated with wire breakage or fiber shedding, protecting high-purity polymer streams from contamination.

Regenerable & Reusable

Suitable for repeated thermal regeneration, vacuum pyrolysis, calcination, ultrasonic cleaning, and chemical cleaning processes.

Typical Applications

  • Polymer Extrusion: Engineering plastics compounding, masterbatch production, and pelletizing systems
  • Recycled Resin Processing: Removal of unmelted particles, cross-linked residues, and contamination from recycled polymer streams
  • Sheet & Film Extrusion: Melt filtration for optical-grade films, barrier sheets, and specialty packaging materials
  • Chemical & Resin Production: Catalyst recovery, post-reactor filtration, and continuous polymer conditioning processes
