Very Low-Density PE (VLDPE)
The PE product line is complemented by the AGRUFLEX VLDPE
geomembranes, which combine the advantages of a HDPE
geomembrane with a high degree of flexibility. Due to its excellent
chemical, physical, and biological properties, this product is suitable
for many applications including tunnel and pond construction.
High-Temperature-Resistant PE (HTRPE)
The maximum continuous operating temperature of HDPE
geomembranes has been limited to a temperature of 140°F (60°C)
until now. At higher temperatures, thermo-oxidative degradation
occurs, resulting in a relatively short service life. AGRU has many years
of experience in piping for hot water and has now incorporated this
knowledge into the development of the HTRPE membrane, which is
able to cope with continuous operating temperatures of up to 212°F
(100°C) and has excellent long-term stability.
Flexible Polypropylene (FPP)
FPP is the latest polyolefin material and was only introduced at
the end of the last millennium. Because FPP does not need to be
manufactured with plasticizers, it is completely homogenous with very
low crystallinity, high strength, and maximum flexibility. In addition,
FPP has a lower coefficient of thermal expansion than PE-based
materials. Thanks to these properties, AGRUFLEX FPP membranes
adapt to the substrate perfectly and are therefore ideally suited to
pond construction.
