In response to a
growing need in the market, Rhovyl has designed a full range of fibers
for various types of filtration.
CHEMICAL
FILTRATION
Being chemically inert, Rhovyl®
fibers
are unaffected by practically all chemical compounds. Concentrated acids and
bases and oxidizing and reducing agents have no effect on them. When the fibers
come into contact with these substances, their mechanical characteristics
remain intact.
Thanks to the great shrinkage potential
of Fibravyl® (60% at
110°C), it is possible to make fabrics with a very tight weave that
strengthens the intrinsic qualities of Rhovyl®
fibers,
resulting in even more effective filtration.
Rhovyl®
fibers
are thus perfectly suited to filtration methods using bleach or hydrochloric
acid and electrolytic processes.
FOOD
FILTRATION
The heat sealing properties
of Isovyl® MPS fiber mean that it can be used in the form of a non-woven
material for filtration of wet or dry foodstuffs (e.g. milk, tea, etc.).
This food-grade fiber is
suitable for use in paper filters for hot or boiling liquids and complies
with the recommendations of the German public health administration and the
US Food and Drug Administration (FDA).
AIR
FILTRATION
Rhovyl® fibers are used in
air filtration due to their natural, permanent non-flammability. The
resulting filters have very good burning behavior (category M1) and fulfill
safety requirements for air filtration equipment in hazardous industrial
environments (e.g. in the coal and oil industries).
In addition, Rhovyl produces
an antibacterial fiber, Thermovyl® ZCB, effective enough to be used for air
filtration. The antibacterial agent built into the fiber itself during
manufacture inhibits the development of bacteria and ensures total asepsis
in the filtered product.
