Q1 What materials are used for polymer screen mesh filters?
They are typically constructed from stainless steel (SUS304, 316L, 904L), nickel, copper, brass, Monel, and Hastelloy wires to suit different chemical environments.
Q2 Why are multi-layer filter screens used in extrusion?
Multi-layer screens provide progressive filtration from large to micro-pores, which stabilizes melt flow pressure and prevents broken strips or uneven product weight.
Q3 What is the filtration rating of these mesh filters?
The standard filtration rating ranges from 25 um to 300 um, depending on the mesh size and weave type used.
Q4 What shapes are available for the extruder screens?
We offer various shapes including round, oval, square, rectangle, and kidney shapes to fit different machine specifications.
Q5 Can these filters withstand high temperatures?
Yes, our polymer screen mesh filters are designed to operate in extreme conditions, with a working temperature range from -200℃ to 800℃.
Q6 How do Plain Weave and Dutch Weave wire mesh differ in application?
Plain weave features a simple structure and high cost-effectiveness for standard needs, while Dutch weave provides fine filtration with high strength and load capacity without requiring backup screens.
