Prevent dust leakage in bag filters with this sealing-tape technology
Testori SpA
This company’s process to automatically bond a polytetrafluoroethylene (PTFE) sealing tape (photo) onto either flat- or double-felled seams in bag-filter fabrication is effective in preventing dust-particle leakage through the pinhole of the sewing stitches and, in the case of thermo-welded seams, to avoid possible contamination due to fibers coming loose from the edges. The PTFE-based sealing tape can be applied on a wide range of polymeric fibers, and is offered in two versions. The High Temperature (HT) variety is capable of withstanding very aggressive working conditions such as in coal-fired boilers and cement plants. The Low Temperature (LT) variety mainly applies to polyester and acrylic. Hall 5.0, Stand C45 — Testori S.p.A., Novate Milanese, Italy
