PPS high temperature resistant, Acid & alkali resistant needle prick filter felt is novel temperature resistant filter material which is produced in such way as using polyphenyl enzyme produced by America Dupont Co. , Ltd. and Teijin Co. , Ltd. in Japan and complying with making process of other high temperature resistant needle felt. PPS fiber has strength integrity keeping ability and inner chemistry resistance, and it can keep good filter property in bad environment and reach ideal use life. PPS has excellent properties in the application of the following situation.
1. Working temperature, instant, limiting oxygen index.
2. The situations with oxygen content of less than 15%.
3. Sulf-oxide in flue gas.
4. Dust gas in flue is humid.
Finishing mode singeing, calendering, heat sizing, PTFE dipping and Taifulong coating
