China Polymer Extruder Screen Mesh Filters - High-Quality Suppliers and Factory for Effective Filtration Solutions
Polymer Screen Mesh Filter Description
Wire mesh Filters are mainly used in plastic recycling machines and plastic extrusion machines in order to remove impurities/particles from molten polymers, which is crucial for ensuring the quality of recycled plastics. They are widely used in the separation and filtration of petroleum, chemical, pharmaceutical, food and other industries.
Screen mesh filters are constructed from full stainless steel wires, nickel wires, copper wires, brass wires, Monel wires, Hastelloy wires and other metal wires using advanced weave technology. The mesh filter screen is a key part in plastic recycling and plastic granule production. It can automatically replace the filter screen to ensure continuous production.
Melt filter screens generally use single or multiple layers of filter mesh as filtration media. The filter mesh ensures the purity of the polymer melt through physical interception. Multi-layer filter screens (such as five-layer stainless steel mesh filters) are sieved step by step through a gradually changing pore size (large pores on the outer layer → micro-pores on the inner layer), synchronously stabilizing the melt flow pressure (fluctuation <±0.5%), reducing broken strips or uneven weight.
Specification
Polymer extruder screen mesh filters are generally made of plain weave and Dutch weave wire mesh. The plain weave wire mesh features a simple structure, is economical to process, offers high cost-effectiveness and can meet most filtration requirements of plastic and rubber industries. In a filter, the Dutch weave wire mesh plays the role of fine filtration without requiring a backup filter screen, featuring high strength, high load capacity, simple structure and long service life.

Frequently Asked Questions (FAQ)
Q
What materials are used to make polymer screen mesh filters?
Polymer screen mesh filters are made from a variety of metal wires including stainless steel (SUS304, 316L, 904L), nickel, copper, brass, Monel, and Hastelloy wires. The choice of material depends on the specific application, operating temperature, and chemical compatibility requirements.
Q
What is the filtration rating range for polymer extruder screen mesh filters?
The filtration rating ranges from 25 to 300 microns (µm), covering a wide range of filtration needs for plastic recycling, chemical fiber, and rubber industries. Custom ratings can be provided based on specific application requirements.
Q
What shapes are available for polymer screen mesh filters?
Polymer screen mesh filters are available in a variety of shapes including round, oval, square, rectangle, and kidney shapes. Custom shapes can also be manufactured to fit specific extruder and filtration equipment designs.
Q
What is the difference between plain weave and Dutch weave wire mesh filters?
Plain weave wire mesh features a simple structure, is cost-effective, and meets most standard filtration requirements in plastic and rubber industries. Dutch weave wire mesh is designed for fine filtration, offering higher strength, greater load capacity, and longer service life — making it ideal for applications requiring precise filtration without a backup screen.
Q
What temperature range can polymer screen mesh filters withstand?
Polymer screen mesh filters are designed to operate across an extremely wide temperature range, from -200℃ to 800℃, making them suitable for both cryogenic and high-temperature polymer melt filtration applications.
Q
How do multi-layer filter screens improve filtration performance?
Multi-layer filter screens, such as five-layer stainless steel mesh filters, use a gradually changing pore size — large pores on the outer layer progressing to micro-pores on the inner layer. This step-by-step sieving stabilizes melt flow pressure (fluctuation <±0.5%), reduces broken strips, and ensures more uniform product weight and higher melt purity.
