Huntsman’s Suprasec MDI used in
pipeline cleaning tools
ROPLAST, a designer and manufacture
of pipeline-cleaning tools, is using methylene
diphenyl diisocyanate (MDI) from Huntsman
Polyurethanes to help keep some of the
world’s major oil and gas pipelines free of
grime, residue and dirt.
Working with Huntsman, Roplast
has created a new line of non-cellular,
polyurethane-based, hot cast elastomers.
This industrial grade plastic is being
employed as a core material in Roplast’s
cleaning pigs. Designed to travel hundreds
of miles inside complex pipeline networks,
these devices are fitted with brushes and/
or magnets to gather up any surplus dirt,
ferrous debris or liquid.
Around the globe, gas and oil suppliers
need to ensure pipelines are kept clean
in order to maintain constant flow rates,
minimise operating costs and extend the
lifetime of their assets. Roplast cleaning
products are recognised as one of the
most effective tools to achieve this. The
company was the first to develop pipeline-
cleaning tools that comply with EU legislation
regarding the use of equipment in explosive
environments. Roplast produces different
sized cleaning pigs that can be inserted into
pipes of any length or diameter.
Covering long distances, Roplast cleaning
pigs are exposed to significant abrasive forces
as they navigate narrow bends and confined
spaces. Core components like cups and
discs therefore need to be made from durable
elastomers that demonstrate outstanding
mechanical properties and excellent dynamic
behaviour, even under extreme conditions.
Elastomers based on MDI from Huntsman
are renowned for offering high levels of
resistance vs abrasion, thermal, hydrolytic
and chemical resistance. They also provide
excellent tensile resistance, good elasticity
and a wide temperature operating range.
Dr Michael Magerstädt, corporate man-
ager marketing industry general at Roplast,
said: “We have been creating polyurethane-
based elastomers for many years but were
looking for an additional MDI supplier that
could partner with us on projects moving
forward. Roplast, a member of the Rosen
group, is a large company with a global
presence. We like to build lasting relationships
with suppliers who have similar capabilities
and Huntsman Polyurethanes had all the
right credentials. We added the team to our
list of suppliers for two reasons; the technical
support they offer and their willingness to
assist us on R&D programmes.”
Alfred Rasche, sales account manager
from Huntsman Polyurethanes, said:
“Initially, we’ll be supplying Roplast
with several tons of MDI every month –
predominantly for use in the manufacture of
its cleaning tools. Over time, however, we
hope that our collaboration will grow.”
Roplast also manufactures intelligent
cast polyurethane products for a variety of
industrial applications.
