INTRODUCTION
The outstanding advantages of needle-punched felt made of polyphenylene sulfide fiber are shown in the following aspects: PPS needle-punched felt, PPS anti-corrosion dust filter bag, PPS high temperature resistant dust filter bag, special filter bag for flue gas treatment
1. Good temperature resistance The melting point is 285℃, the continuous use temperature is 190℃, and the instantaneous use temperature is 230℃.
2. Excellent corrosion resistance. Polyphenylene sulfide fiber is superior to Nomex Conex and Kermel fiber in resistance to organic acid, inorganic acid, acid, oxidant, etc.
3. The extreme oxygen index LDI of the excellent flame retardant polyphenylene sulfide fiber is 34-35, and the PPS needle felt is an insoluble material. Polyphenylene sulfide fiber needle-punched felt not only has high temperature resistance, but also has unique properties of anti-corrosion.
