Handling Corrosive Water
with Kynar® PVDF
W
astewater generated in chemical processes
can create difficult challenges for
standard materials of construction. The combination
of many different acids, chlorides, bases,
and solvents can quickly oxidize and corrode
common metallic materials and severely soften,
swell, or crack traditional polymers. Fluid
handling components made from Kynar PVDF
and Kynar Flex PVDF have been used for many
years in the most demanding applications.
The broader range of chemical resistance of
F
lottweg is one of the world's leading manufacturers of industrial
centrifuges. The company, headquartered in Vilsbiburg,
achieves an annual turnover of over 169 Million Euros with an export
rate of more than 85 %. Flottweg has own subsidiaries and
branch offices with service centers in the US, in People's Republic
of China, in Russia, Italy, Poland, France, Australia and Mexico.
Concentration on customer requirements, keen sense on how
markets will develop, and the ability to come up with creative solutions
have helped to make Flottweg one of the world's leading
producers of centrifuges for separation technology. In order to secure
the market position for the future, Flottweg will continue to
upgrade its technology, provide the highest quality products and
provide 24-hour aftermarket service.

Kynar PVDF compared to other polymer materials has led to complete
product lines of piping, fittings, tubing valves, pumps, tanks, nozzles
and filtration components that can be employed to handle varied
concentrations of some of the most aggressive corrosive chemicals.
In addition to the excellent chemical and permeation resistance,
Kynar PVDF is 150°C RTI rated, ASTM E84 (25/50) compliant, inherently
sunlight resistant, and highly abrasion resistant. Due to the
thermoplastic nature of Kynar PVDF, it is light weight and very easy to
fabricate by common heat methods like welding and thermoforming.
Mechanical joining methods and threading are also possible.
Examples of Kynar PVDF in waste drain and exhaust systems
span several industrial market segments.
* Petrochemical - combinations of aromatic and aliphatic hydrocarbon
mixtures including sulfur, brines, and acids
* Food & Beverage - chlorinated cleaning agents, acidic sanitization
chemicals, and alcohols
* Nuclear Clean Up - acids, radioactive materials, and chlorinated water
* Biotech & Pharmaceutical - Bromides, chlorides, acids, and alcohols
* Pulp & Paper - bleaching chemicals, acids, and brines
* Mining & Metal Preparation - hot acids
* Semiconductor - peroxides, acids, and sulfate solutions
* University Laboratories - ASTM E84 flame and smoke compliance,
virtually unlimited chemical combinations
Solid or supported piping systems with various joining methods
are readily available up to 12 inch diameter, and these are
complemented by multiple
types of valve and
pump designs made
from Kynar PVDF to
connect the whole system.
Holding vessels
or other containment
items can also be constructed
by rotomolding
or by welding sheets of
the required thickness
together.
PVDF is the only
Fluoropolymer available
with a very broad range
of stiffness options for
anything from highly
flexible tubing to rigid
self-supporting pipes.
New grades of glass
fiber composites called Kynar UHM PVDF can increase the already
high strength of the base material by up to 3 times higher flexural
modulus. These grades are being used for fasteners, pump bodies
and structural supports in fluid separation.
