Pleated Sintered Filter Element for Polymer Melt
1. Product Overview
The Pleated Sintered Filter Element is specially designed for high-temperature, high-viscosity, and high-pressure polymer melt filtration. It is made from stainless steel sintered fiber felt or multilayer woven wire mesh, structured into a pleated cylindrical form to significantly increase filtration area and contaminant holding capacity.
This advanced filter is widely used in chemical fiber, plastic, film, battery, petrochemical, and precision chemical industries as a high-efficiency upgrade over traditional mesh screen filters.
2. Structure & Materials
-
Filtration Media: Sintered metal fiber felt or multilayer wire mesh
-
Support Layer: Coarse stainless steel mesh for structural reinforcement
-
Shell & Core: Stainless steel 304/316L/904L, Hastelloy, Titanium, etc.
-
Connection Options: International standards 222/226/220, threaded, flange, clamp, or custom end connections
The pleated construction provides 5–10 times more filtration area than conventional smooth filters, enhancing flow capacity, reducing pressure drop, and extending filter life.
