PTFE membrane Polyester needle felts
PTFE membrane polyester needle filter felt has a gloss surface and has good resistance of chemical substance. It can also be laminated to the surface of ordianry needle filter felts like polyester needle filter felts. The dust is trapped in the entire membrane surface to achieve surface filtration; It has excellent chemical stability , slow-aging, and water-repellent, improve the usage of the needle filter felts.
