Aramid (MX)
Aramid Offers a Good Resistance to Alkalis.
Guide to Aramid Filter Bag Applications
Aramid Felt (common brand: Nomex®) Normal maximum continuous operating temperature is 375°F. General applications for Aramid felt include: highly abrasive dust applications, electric arc furnaces, high-temperature dryers, cupolas, and chemical applications where high temperatures exist. Aramid offers a good resistance to alkalis under most conditions. Most mineral oxides cause degradation and partial decomposition. Aramid withstands common organic solvents very well. Some phenolic compounds cause solubility.

Aramid Felt Common Finishes
Singed (SIMX) – 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 (GLMX) – 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.
