Tensile Strength ≥290MPa ≥340MPa ≥370MPa ≥510MPa ≥500MPa
Yield strength - ≥175MPa ≥215MPa ≥380MPa ≥355MPa
Standard JIS G3445
Length As customer's request
Packaging Standard export packing, packed in woven bags, with two nylon slings, or can be customized as request
Heat Treatment/      Delivery Condition Cold finished (hard)   BK(+C)
Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation
Cold finished (soft)    BKW(+LC)
The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding)
Cold finished and stress-relieved annealing BKS(+SR)
Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.
Annealed    GBK(+A)
The last Cold forming process is followed by annealing in a controlled atmosphere.
Normalized   NBK(+N)
The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
Delivery Time Within 35-50 days from receiving deposit
Payment Term 100% L/C at sight or 30% deposit, 70% balance against copy of B/L
Usage/Application Pipes for automobile and motorcycle
Main Market Asia, Middle East, Europe, etc.

Smooth Geomembrane

HDPE smooth Geomembrane is one double-surface membrane with flat and smooth appearance made from virgin resin with special formula. We can produce HDPE geomembrane, LLDPE geomembrane, LDPE geomembrane etc. HDPE glossy geomembrane has excellent impermeable and antifouling property and mechanical property; dimensional stability, chemical stability, thermal resistance and aging resistance are good; in the meantime, it also has excellent resistance to UV radiation.

Waterproof HDPE geomembrane

The Application of HDPE geomembrane

1) Environmental protection sanitation (such as solid waste landfills, sewage treatment plants, power plants Chi-conditioning, industrial, hospital solid waste, etc.) .

landfill application of geomembrane

2) Water (such as rivers, lakes and reservoirs of the anti-dam, plugging, reinforcement of the canal seepage, the vertical wall of the heart, slope protection, etc.).

pond liner

3) Municipal Engineering (subway, on the ground floor of the building, planted roof, the roof garden of anti-seepage, sewage pipes lining, etc.).

HDPE geomembrane welding

4) Landscape (man-made lake, river, reservoir, golf courses reservoirs of the substrate, slope protection, green lawn of the waterproof moisture, etc.).

HDPE geomembrane for landfill

5) Petrochemical (chemical plants, oil refineries, gas storage tanks of the anti-chemical reaction tanks, sedimentation tanks of the lining, etc.).

hdpe geomembrane construction

6) Mining (washing and pool heap leaching, the ash-field, dissolved, precipitation, the yard, the tailings seepage substrates, etc.)
