Stainless steels and super alloys from Höganäs possess excellent properties for hot polymer filtration. They do not react chemically with the polymers and they are strong enough to minimize compaction during filtration.

The powder processing - high-pressure water atomization - results in extremely irregular shaped particles. Irregular shapes provide large active surface areas, which ensure good cleaning during filtration and a porous structure with deep filtration properties that remains unchanged during the filtration cycle. Additionally, the powders are not so hard, which prevents brittleness and thereby nozzle clogging. All these factors combine to make Höganäs products for spin packs a cost-effective solution for the hot polymer filtration industry.
