Trelleborg Sealing Solutions launches its Isolast K-Fab Seal designed to provide long-term sealing and increased productivity in high-temperature semiconductor subfab applications. The Isolast K-Fab Seal provides an alternative flange sealing solution to a traditional O-Ring, to prevent premature failure in extreme temperatures and aggressive chemical environments. Formulated from perfluoroelastomer (FFKM), a custom seal geometry utilizes significantly less rubber to eliminate overfill and extrusion, resulting in improved thermal properties, and elimination of thermal expansion and groove overfill. The seal geometry can withstand misalignment of the flange when compared to an O-Ring, for easy assembly. This optimal seal design increases performance, especially with varying pressure or vacuum conditions for increased service life and overall lower cost of ownership.
The Isolast K-Fab Seal is temperature resistant for use up to +325 °C / +617 °F dependent on the material selection. Flexible use of elastomer materials is intended to lower the overall cost of ownership by matching the material performance with the application. Suitable for combination with both aluminum or stainless steel, the Isolast K-Fab Flange Seal can be manufactured from a range of elastomer materials including Isolast FFKM, Isolast PureFab FFKM for ultra-high purity, FKM, and PureFab FKM.
