Hot Polymer Filtration
Stainless Steel powders
Metal powder filter packs
The metal powder is composed of grain particles with a specific shattered shape. This offers the key benefit over mineral sand or glass beads of providing a good tradeoff between porosity volume and active surface area. Höganäs recommends the P-270 grade, a stronger alloy compared to standard stainless steel 316L.
To improve the yarn quantity, Höganäs recommends the P-271, a grade nobler and less oxidization-sensitive than standard stainless steel grade during pre-heating of the packs, a must for high-quality nylon production. For high pressure filtration, DP-1 is promoted for its high compaction resistance, thermal stability and its magnetic properties, as a nickel-free metal alloy.
