Hot Polymer Filtration
Stainless Steel powders
Spin-pack filter media
The filters are normally made of woven or non-woven stainless steel fibres. These are strong and inert to hot polymers, characteristics that are mainly determined by the alloy used. The drawbacks are a low porosity level and a quite small surface area for a given volume.
This inexpensive filter medium is strong and, if well cleaned, inert to hot polymers. Due to the rounded shape of the particles, it does not offer a high porosity level or a large surface area. The silica sand tends to crack under high pressure and forms very fine particles that clog the holes during filtration.
This relatively inexpensive filter medium is strong and inert to hot polymers. The particles are round, which gives a low ratio between the active surface area and the porosity volume. Under high pressure, the glass beads tend to crack and consequently form very fine particles that clog the holes during filtration. We provide an alternative filter medium; specially designed corrosion-resistant metal powders that can be used as an excellent substitute or complement to the above-mentioned products
