Solvents

The filtration of solvents; the search for the filters that are resistant taking into account the important factors of contact time and temperature.

The available tables for chemical compatibility are only guidelines referring to solid materials.
However, a filter medium consists of a fine fibre structure and thus has an enormously large contact surface for the solvent. The potential impact of a solvent will be much greater than for a solid material.

The temperature of the solvent will have an important influence. A temperature of 20°C or 60°C can give very different results.
The contact time of the solvent with the filter is another critical factor; e.g. 2 hours could be OK, while a duration of 6 hours could damage the filter.

It becomes even more complicated when you know that some filter cartridges consist of different materials.
For example:
end caps made of polypropylene
support layers of polyester
membrane of PES

To be absolutely sure, all of this needs to be tested and we can help you with that.

Arranged has filter cartridges that are made of 100% Polypropylene, 100% Polyester or 100% Nylon.

Feel free to contact us with your projects about filtering solvents.
