Product Description

(LLDPE)Geomembrane--soft popythylene

Specification: Width: 2000-7000 mm, Thickness: 0.5-3.0 mm

Perform standard: GRI-GM17

Single-double side textured soft geomembrane, is on the basis of smooth geomembrane spraying from a special geomembrane Select a special linear low density polyethylene (LLDPE) resin, using patented technology to produce high quality geomembrane, generally asperity height is 0.25 mm, with more extend the performance and flexibility. Very suitable for uneven settlement or partial settlement of the project, due to increase asperity height on the surface, can better integrate and other materials, better use of the slope in the larger works. Such as mine heap leaching field, landfill closures and other field extension of the material properties and puncture resistance requirements of high-intensity projects. Singledouble side textured soft geomembrane compare with textured HDPE geomembrane, Some forms can be complex and the need for deformation of the environment, such as: culverts, drainage water to the geomembrane bending relatively large projects. The charaders meet or exceed performance standards GRI GM17.

(1)Of 10 readings; 8 out of 10 must be≥0.18 mm, and lowest individual reading must be≥0.13 mm

(2)Alternate the measurement side for double sided textured sheet

(3)Machine direction (MD) and cross machine direction (XMD) average values should be on the basis of 5 test specimens each direction.

·Break elongation is calculated using a gage length of 50 mm at 50 mm/min.

(4)Other methods such as D 4218 (muffle furnace) or microwave methods are acceptable if an appropriate correlation to D 1603 (tube furnace) can be established.

(5)Carbon black dispersion (only near spherical agglomerates) for 10 different views:

·9 in Categories 1 or 2 and 1 in Category 3

(6)The manufacturer has the option to select either one of the OIT methods listed to evaluate the antioxidant content in the geomembrane.

(7)It is also recommended to evaluate samples at 30 and 60 days to compare with the 90 day response.

(8)The condition of the test should be 20 hr. UV cycle at 75℃ followed by 4 hr. condensation at 60℃.

(9)Not recommended since the high temperature of the Std-OIT test produces an unrealistic result for some of the antioxidants in the UV exposed samples.

(10)UV resistance is based on percent retained value regardless of the original HP-OIT value.
