Resin pipes achieve highest chlorine
resistance classification
Dow Europe GmbH has announced
that pipes manufactured with Dowlex™
2388 PE-RT (polyethylene of raised
temperature resistance) resins have
received the highest chlorine resistance
certification (Class 5). The certification
was issued by Jana Laboratories,
Canada, and conducted on pipes
in accordance with the conditions
specified in ASTM F20231 and ASTM
F2769-102.
The Dowlex™ 2388 PE-RT extruded
plastic pipes were submitted to different
temperatures and pressures at a
chlorine concentration of 4.4 ppm and
were tested for more than two years
until a failure could be observed. The
results allowed extrapolation to lower
temperatures, and the pipes exceeded
the requirement of 50 years at 60°C at
such high chlorine concentration.
Alex Stolarz, senior development
engineer at Dow Performance Plastics,
commented, “Dowlex™ 2388 PE-RT
resins have a unique molecular structure
which makes them highly resistant to
the oxidation caused
by chlorinated water.
As a consequence,
the resins are most
suitable for plumbing
pipes conducting water
subject to disinfection
techniques. Chlorine
resistance is also a
requirement for some
of the drinking water
markets around the
globe. We are extremely
happy with the test
results. With the proven
chlorine resistance we can offer our
customers a solution which enables
them to extend their product offering to
new markets.”
Pipes manufactured with PE-RT resins
have the ability to be welded, enabling
connection through inexpensive,
injection-moulded connectors. Surface
smoothness of the end product also
means reduced pressure loss and
less deposit formation, meaning less
maintenance is required.
Using PE-RT resins can also improve
recycling potential compared to
alternative materials, and the reduced
energy demand during processing has
the potential to improve the overall CO 2
footprint of the end product.
