This 80µm high efficiency nickel tube is manufactured from high-purity nickel powder through vacuum sintering, achieving an 80µm filtration rating. Nickel remains chemically inert in high-temperature polymer melts, exhibiting no catalytic activity that could cause polymer degradation or cross-linking. This material property ensures molecular weight stability of the filtered melt. The uniform three-dimensional pore structure enables deep filtration mechanism with narrow pore size distribution, providing efficient retention of gel particles, carbides, and catalyst residues while maintaining consistent melt flow.

The sintered neck structure delivers exceptional compressive strength and thermal shock resistance, withstanding pressure fluctuations and temperature variations during melt extrusion without structural deformation over extended operation. This nickel sintered tube supports online backflush regeneration capability with high flux recovery after cleaning. It is suitable for continuous filtration processes in polyester, polyamide, and polyolefin systems, serving as a critical component in melt filtration systems to ensure quality consistency in spun, film, and extruded products.

product Features

1. Stable Performance Under High Temperature

The porous tube produced from high-purity nickel powder maintains structural integrity when exposed to elevated temperatures in polymer melt processing. This stability helps ensure consistent filtration performance during continuous operation.

2. Excellent Chemical Compatibility
Nickel exhibits strong resistance to chemical interaction with various polymer systems. This characteristic minimizes the risk of unwanted reactions with additives or residual compounds in the melt, helping maintain material purity.

3. Uniform Porous Structure for Efficient Filtration
The engineered pore network provides consistent pore distribution, enabling reliable removal of gel particles and fine contaminants. This contributes to improved quality consistency in downstream polymer products.

4. High Mechanical Strength
The metallurgical bonding formed during sintering creates a rigid structure with strong resistance to compression and pressure variations, making the tube suitable for demanding extrusion environments.

5. Good Permeability for Stable Flow
While delivering effective filtration, the interconnected pores allow polymer melts to pass through smoothly, helping maintain steady flow conditions in the processing line.

6. Reusable and Easy to Clean
The durable metal structure supports cleaning methods such as reverse flushing, allowing the filtration element to regain permeability and extend its service life in industrial applications.

Typical Applications in Polymer Melt Filtration Systems

1. Polyester Melt Purification

Used in polyester processing lines to remove micro-contaminants from molten material. This helps stabilize spinning and film forming operations.

2. Filtration in Polyamide Processing

Applied in nylon extrusion or spinning systems to separate solid residues from the melt stream. Cleaner melt improves forming stability and product consistency.

3. Polyolefin Extrusion Line Filtration

Installed in polyethylene or polypropylene extrusion equipment to capture fine impurities. This reduces wear on dies and improves surface quality of finished products.

4. Fiber Spinning Melt Purification

Integrated into synthetic fiber production systems to refine molten polymer before spinning. The process helps maintain uniform fiber structure.

5. Film Extrusion Melt Filtration

Used in plastic film manufacturing lines to prevent insoluble particles from reaching the die area. This contributes to smoother and more uniform film output.

6. Online Filtration in Continuous Extrusion

Suitable for continuous polymer processing equipment where stable melt purification is required. The filtration element supports long operating cycles with reliable performance.
