High Density Polyethylene (HDPE) Sheets
It is used in Textile Ind. for making Spinning Cans,
Packaging Application, Automobile spars, Luggage Ind., Crates Partition,
Thermoformed Parts, Water Treatment plants, Landfill, Pond lining, Oil Trap
Pit Lining & for fabrication of Vessels Ducting, Tanks lining.
Chopping Board & Butcher Blocks are manufactured from premium food
grade high-density polyethylene. They are offered for home use to commercial
food preparation. These boards are smooth for trouble free chopping, slicing
and cutting & friendly with knife. They will not chip, crack or warp and
are non-porous, non-absorbent and stain- resistant.
Cutting / Clicking Boards are offered in High Density Polyethylene for
industrial, commercial as well as domestic applications with a surface that
is easy on cutting blades. These boards possess high impact and absolute
dimensional stability characteristics along with perfect combination of
material-cut feature. The boards are used on automatic and semi-automatic
cutting presses, die-cutters and cutting machines, roller presses &
High Density Polyethylene (HDPE) liner :
High Density Polyethylene (HDPE) liner is the most
widely used geomembrane in the world due to its inexpensive material cost.
HDPE lining material is an excellent product for large applications that
require UV and Ozone resistance, chemical resistance or high-quality
installations. One of the main uses of HDPE is for landfill base liners,
Waste lagoons, Pond lining, Aquacultures and mining applications where its
chemical resistance is used to good effect. HDPE is best used as an exposed
lining material, and has the UV resistance required for many years of
HDPE Geomembrane Sheet :
HDPE Geomembrane Sheet product is delivered in large
rolls with a width of 1500mm and is a field assembled lining material that
cannot be practically fabricated in the shop. All HDPE projects, regardless
of size, must be installed by trained installers. HDPE offers the most cost
effective liner for large projects. HDPE is available in thicknesses ranging
from 0.70mm to 5mm.
HDPE Geomembranes Liners :
HDPE Geomembranes Liners are manufactured from a
nonpolar thermoplastic polymer which is chemically very stable but forms a
melt above 140 °C, and so can be extruded at approximately 200 °C.
Therefore in practice, HDPE geomembranes sheets cannot be glued by chemical
processes and welding by thermal process is the jointing technology of
Description of Welding Methods :
Areas to be seamed shall be free from dust\debris and
dry. In no case shall HDPE Sheet overlap be less than 75mm HDPE Geomembranes
sheets are to be sufficiently overlapped up to 150mm to secure sufficient
Weather conditions can be of extreme influence to the weld quality;
therefore welding or Seaming is prohibited during rain without special
protection. Seaming is usually prohibited at temperatures of less than + 4°c
and above + 75°c. Subgrade must be maintained in good condition to
guarantee permanent bearing capacity (in case welding equipment is dependent
on ground pressure). Prior to commencement of welding, test welds are to be
executed and tested to all weld parameters.
No vehicular traffic shall travel on the HDPE geomembrane sheet other than
an approved low ground pressure Vehicle or equivalent
Sand bags or equivalent ballast shall be used as necessary to temporarily
hold the geomembrane material in position under the foreseeable and
reasonably - expected wind conditions.
Geomembrane placement shall not be done if moisture prevents proper
subgrade preparation, sheet placement, or sheet welding.
The HDPE geomembrane shall not be allowed to "bridge over" voids
or low areas in the subgrade. The HDPE geomembrane shall rest in intimate
contact with the subgrade.
Welding or Seaming shall primarily be performed using automatic fusion
welding equipment and techniques. Extrusion welding shall be used where
fusion welding is not possible such as at pipe penetrations, patches,
repairs and short (less than a roll width) runs of seams.
Welding or seaming of HDPE Geomembrane is a thickness dependant technique
that requires a minimum material thickness to create an effective weld
without distortion. Extrusion welds in sheet less than 1.0 mm thickness are
not recommended. Extrusion welds in 1.0 mm thick HDPE Sheet show some
distortion and can sometimes be very difficult to prepare around intricate
pipe penetrations and mechanical attachments. 1.5 mm thick HDPE Geomembrane
sheet can be reliably extrusion welded in most situations and is recommended
in most applications. Welds in 2.0 and 2.5 mm thick HDPE Sheet are excellent
and are recommended in applications that require exceptional durability.
Extrusion welds are very slow and are typically used only for repairs and
Hot wedge welders have become the technique of choice for HDPE installers
over the past several years. Wedge welders are fast, produce excellent welds
in HDPE sheet from 1.0 mm to 2.5 mm thickness, and can be easily tested. Hot
wedge welders today produce two weld tracks separated by a small unbonded
channel. By sealing off both ends of this channel, and then pumping it full
of air, entire seams can be checked quickly and effectively.
Fishmouths or excessive wrinkles at the weld or seam overlaps shall be
minimized and when necessary cut along the ridge of the wrinkles back into
the sheet so as to effect a flat overlap. The cut shall be terminated with a
keyhole cut nominal 10 mm diameter hole so as to minimize crack/tear
propagation. The overlay shall subsequently be welded. The key hole cut
shall be patched with an oval or round patch of the same base HDPE Sheet
geomembrane material extending a minimum of 150 mm beyond the cut in all
