hdpe geomembrane with textured surface
1.Brief introduction: Li Yuan single-double side Textured high density polyethylene (HDPE) geomembrane are made by excellent high densityPolyethylene resin, it uses of invention patents made. In addition to the products is high-density smooth performance,but also has a higher anti-ultraviolet capability, apply to the open-air environment. Increase the coefficient of friction, bettersuited to steep slopes and vertical engineering design needs, improve project stability.
2.Specification: Width: 2000-7000 mm, Thickness: 0.75-3.0 mm, can also be customized according to requirement.
3.ASTM test report of Textured HDPE Geomembrane:

Description:
1) 0.18mm, the minimum value should be greater than 0.13mm. Two-surface roughness of the geomembrane should be carried out alternately in the two measurements. 2) 10 observed in the region should belong to the 9th grade in the first or second grade; third grade should not belong to more than 1.
3) According to the specifications of the quality of per unit area, the actual specifications in the range of specifications between the adjacent table, according to the interpolation method to calculate the appropriate evaluation indicators; beyond the scope of the table, the assessment indicators to be negotiated by the supply and demand. 4) The value of the standard design or by agreement. 5) If the above indicators data change without notice. 6) According to user requirements specifications for the production of other products.
