High-Quality Polymer Extruder Screen Mesh Filters - China Suppliers & Factory for Efficient Filtration
Polymer Screen Mesh Filter Description
Wire mesh Filters are mainly used in plastic recycling machine and plastic extrusion machine in order to remove impurities/particles from molten polymers, which is crucial for ensuring the quality of recycled plastics. It's widely used in the separation and filtration of petroleum, chemical, pharmaceuticals, food and other industries.
Screen mesh filter is constructed from full stainless steel wires, nickel wires, copper wires, brass wires, Monel wires, Hastelloy wires and other metal wires by using advanced weave technology. The mesh filter screen is a key part on the plastic recycling and plastic granules 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 ensure the purity of the polymer melt through physical interception. Multi-layer filter screens (such as five-layer stainless steel mesh filter) 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 filter is generally made of plain weave and Dutch weave wire mesh. The plain weave wire mesh features simple structure, economic to process and high cost-effectiveness and can meet the most filtration requirements of plastic products 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
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, selected based on the specific filtration requirements and operating environment.
What is the filtration rating range for polymer extruder screen mesh filters?
The filtration rating typically ranges from 25 to 300 microns (μm), covering a wide spectrum of filtration needs from coarse to fine filtration in polymer melt processing applications.
What is the difference between plain weave and Dutch weave wire mesh filters?
Plain weave wire mesh features a simple structure, is economical to produce, and offers high cost-effectiveness suitable for most plastic and rubber filtration needs. Dutch weave wire mesh provides finer filtration, higher strength, greater load capacity, and longer service life, making it ideal for precision filtration without requiring a backup filter screen.
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 to accommodate different machine configurations and application requirements.
What temperature range can polymer extruder screen mesh filters withstand?
These filters are designed to operate across a wide temperature range, from -200℃ to 800℃, making them suitable for both cryogenic and high-temperature polymer processing environments.
What industries use polymer screen mesh filters?
Polymer screen mesh filters are widely used in plastic recycling, plastic extrusion, chemical fiber production, rubber manufacturing, as well as petroleum, chemical, pharmaceutical, and food processing industries where separation and filtration of molten or liquid materials is required.
