Polyester Felt Popular Finishes:
Singed Polyester (SIPE) – The felt is singed on the dust cake side for improved cake release. Most common type of filter media used in modern baghouses. 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 Polyester (GLPE) – 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 dust cake release.
SlyTech-01 (ST-01) – Oleophobic -water and oil repellent finish. SlyTech-01 is a complete PTFE bath which provides an excellent cake release finish to each fiber. This finish is cheaper and more durable than a membrane that can be easily scratched.
