Product Description

Description
The melt filter element is installed in the extrusion line, where the polymer melt is forced through the filter to remove impurities. The filtered polymer melt then proceeds to the spinning process, where it is solidified into continuous filaments or staple fibers.
The main filter layer of Pleated Filter mainly uses two materials: stainless steel wire mesh and stainless steel sintered fiber. Stainless steel wire mesh is woven from stainless steel wire. Its pleated filter has the characteristics of smooth pores, easy cleaning, high temperature resistance, corrosion resistance, no wire mesh falling off, and long filtration cycle. Stainless steel sintered fiber is a porous deep filter material made of stainless steel fibers sintered at high temperature. Its pleated filter has the characteristics of high porosity, good air permeability, strong dirt holding capacity, and strong regeneration ability.

Frequently Asked Questions
Q What materials are used in the pleated candle filter?
The pleated candle filter primarily uses two filter media: stainless steel wire mesh (woven from stainless steel wire) and stainless steel sintered fiber (a porous deep filter material made by sintering stainless steel fibers at high temperature). Both are available in SUS304 and SUS316L grades.
Q What is the filtration rating range of the polymer candle filter?
The polymer pleated candle filter supports a filtration rating range of 1 to 200 microns, making it suitable for a wide variety of polymer melt filtration applications with different purity requirements.
Q What is the maximum working temperature the filter can withstand?
The polymer candle filter is designed to operate at temperatures up to 350°C (≤350℃), making it well-suited for high-temperature polymer melt processing environments such as polyester and nylon spinning lines.
Q What connector types are available for the candle filter?
The filter supports a wide range of connector types including 222, 226, 215, M36, M28, M24, M22, and M20, allowing easy integration into most standard industrial filtration systems and housings.
Q Can the polymer pleated candle filter be customized?
Yes. High quality polymer pleated candle filters can be manufactured to meet specific requirements of polymer melt filtration applications, including custom filter lengths (16–60 inches), filtration ratings, and connector types.
Q In which industries is the polymer candle filter commonly used?
The polymer candle filter is widely applied across multiple industries including petrochemical (refining and chemical production), metallurgy (hydraulic systems for rolling mills), textile (polyester melt purification), electronics and pharmaceuticals (water treatment and glucose filtration), as well as thermal and nuclear power (lubrication and control system purification).
