Geomembranes
Borstar® LLDPE enables easy processing, excellent gauge variation and high-output rates in geomembrane applications
Growing concerns over waste have helped open a new
market for cast- and blown-film processors in many countries.
In order to prevent pollution of ground water supplies, for example, many landfill areas now rely on protection by geomembranes. These thick, flexible, high-quality films need to provide puncture protection, withstand pressure, and exhibit high chemical and UV resistance.
Borealis has developed a range of Borstar® LLDPE grades for use in producing geomembrane applications through blown or calendar stack film extrusion. Geomembranes are typically produced from PVC or HDPE, but very-low-density PE and polypropylene are also being processed for this purpose. A typical geomembrane is 1.5-3 mm. thick and extruded in widths of from 4-8 metres.
Our Borstar LLDPE material grades deliver a range of benefits including:
-
easy processing,
-
high output rates,
-
mechanical properties,
-
excellent gauge variation,
-
smooth surface,
-
down-gauging potential for thinner liners,
-
excellent distribution of carbon black,
-
consistent quality,
-
flexible liners, no need for blending plus higher quality,
-
broad sealing window,
-
no wrinkles or “banana curves” after unwinding,
-
high mechanical strength,
-
low failure rate.
The main geomembrane applications are:
-
landfill liners,
-
capping liners,
-
mining liners,
-
building & construction liners,
-
pond/aquaculture liners,
-
canal liners.
