KEE geomembrane for a secondary
containment application with a soil cover

Uses and applications
While a variety of flexible vinyl applications were initially pursued using KEE,
geomembranes are the first commercial
use for KEE. Performance after direct
contact with aggressive fluids was a good
way to demonstrate and confirm the
resistance of KEE to plasticizer migration
in harsh environments. As a result of the
excellent geomembrane performance in
exposed applications, single-ply roofing
products with KEE were subsequently
introduced. This has resulted in significant penetration of exposed roofs for
commercial structures.

Strengths
KEE plasticizers/polymers enhance the
characteristics of other resins by making
them more durable, more flexible and

longer lasting. Typical benefits of KEEblended materials include:
* Improved performance under conditions in which a liquid plasticizer would
migrate, such as outdoor exposure to
weather or contact with chemicals. As
a result, EIA or EIP geomembranes are
being used for hydrocarbon and diesel
containment applications.
* Increased melt strength for thinner
parts, improved foam cell structure
and increased thermoforming temperature window, which has facilitated welding individual sheets of
EIA geomembranes.
* Reduced scrap and higher yields
through improved flow and fusion
characteristics, which allows for lower
processing temperatures and a wider
processing window for rigid PVC
resin/materials.
