PPS (Polyphenylene Sulfide)
Suited for Applications Where Emissions Standards Are Tight.
PPS: High-Performance Material for Industrial Applications
PPS (polyphenylene sulfide) – Normal maximum continuous operating temperature is 375°F. Common applications include coal-fired boilers, incinerators, fluidized bed systems, cement mills, oil and gas firings, asphalt plants, and pulverized coal injection systems. Ryton® has excellent resistance to both acids and alkalis. The media also can operate effectively on applications with O2 content up to 9%. Ryton® works well in high moisture content applications and where dew point crossings are common. This media is suited for applications where emissions standards are tight.
Common brand of PPS include Ryton® and Procon®.

PPS Common Finishes
PTFE Membrane (TX-XP) – For extreme application, the PTFE filter bag’s efficiency and cake release are further improved with a thin membrane of PTFE applied to the felt. A PTFE filter with a PTFE membrane gives maximum emissions protection.
Singed (SIPPS) – The felt is singed on the dust cake side for improved cake release. The process involves exposing the surface fibers to an open flame that melts back the loose fiber ends to which dust particles could adhere.
Glazed (GLPPS) -This process involves running the felt through two heated rollers to melt back the loose fiber ends, improving the cake release. The process can also compress the felt to smooth the surface, further improving the cake release.
SlyTech-01 (ST-01) Oleophobic -water and oil repellent finish. SlyTech-01 is a complete PTFE bath that provides an excellent cake-release finish to each fiber. This finish is cheaper and more durable than a membrane that can be easily scratched.
