Frit Volume – Stainless, Titanium, and Polymer Frits
Internal frit volumes are theoretical and are calculated by multiplying the total frit volume by the proportion of the pores in the frit (porosity proportion). Stated frit porosities are only nominal and do not relect the maximum pore size of a frit. The chart below will help you in selecting the right frit for your application.
| Porosity in µm |
Max pore size in µm |
Particles retained in µm |
Porosity in % |
|---|---|---|---|
| 0.2 | 1 | ≥ 1.0 | 22 |
| 0.5 | 2 | ≥ 1.5 | 26 |
| 1 | 3 | ≥ 3.0 | 30 |
| 2 | 5 | ≥ 3.5 - 5.0 | 35 |
| 5 | 15 | ≥ 15.0 | 38 |
| 10 | 30 | ≥ 30 | 40 |
