Bekipor® sandless spinpack media

Bekaert Bekipor sandless spinpack media
Bekipor® sandless spinpack media is an innovative alternative to metal sands or powders used in spinpack applications. The medium consists out of sharp triangular metal fibers with a high surface to volume ratio. Bekipor® is highly adaptable. Depending on your filter requirements and design, dimension, composition, shape and alloys can be easily customized.

Enhanced gel shearing

Bekipor® particularly benefits filter applications that use gel-prone polymers, for instance for the production of filaments and films. The compactness of the media ensures a very short polymer residence time within the spinpack. Its sintered composition eliminates the risk of channeling, compaction and nozzle blockage associated with the use of sand. Bekipor®’s enhanced gel shearing properties result in better fiber quality and reduces contamination that can lead to defects like fish-eyes in films.

Proven quality

The pressure and lifetime of sand filled and sandless spinpacks have been thoroughly tested. The tests not only showed that the fiber quality in polyester and nylon lines was equal or better than sand, the on-stream lifetime of the filter media is also significantly longer.
