further steps up its activities
in the attractive membrane business.
The specialty chemicals company recently
started operating a thin-film composites plant
to coat membranes for use
in organic solvent nanofiltration and
gas separation at its Marl site in Germany.
Evonik is a global leader
in the area of organic solvent nanofiltration,
an innovative technology for particularly effective
material separation in organic solvents.
The Group’s hydrophobic polyimide membranes,
are used in processes such as
the efficient recovery of valuable homogeneous catalysts,
solvent recycling, or gentle processing of natural oils.
In the new thin-film composite plant, thin membrane films
are coated with special silicone or other materials.
The resulting composite membranes
are then turned into solvent-resistant or
gas-tight spiral-wound modules
in a further production process.
The corresponding silicone coating, also
manufactured by Evonik, is a key factor
for the separation properties of the membrane.

Access to advanced membrane technology
"The start-up of the thin-film composite plant
is a consistent step in our growth plan
for the attractive membrane business,"
"It gives our customers direct access
to an advanced membrane technology
for resource-efficient material separation."
