  • Detail

Description:

HDPE geomembrane ( high density polyethylene geomembrane) use high-quality polyethylene virgin  resin, the main component of 97.5% of high density polyethylene, about 2.5% of carbon black, anti -aging agent, antioxidant, uv absorber and stabilizer ; Tai'an Taidong introduced ultra width automatic  HDPE antiseepage geomembrane production equipment, all products produced according to the  GRI standards and ASTM testing standards. We have completed specifications, smooth surface and  textured surface, thickness from 0.10 mm to 4.0mm, width can be up to 10 m, the HDPE geomembrane  can completely meet the application requirements of Environmental Sanitation, Water Conservancy,  Construction, Municipal Engineering, Landscape, Petrochemical, Mining, Salt, Agriculture, Aquaculture.


Product Features:

Good physical and mechanic performance.

High tearing resistance, strong deformation adaptability.

Puncture-resisting, aging resisting, ultra-violet radiation, oil and salt, and corrosion resistance.

Good adaptability to high and low temperature, non-toxicity, long service life.

Good waterproof, drainage, anti-seepage and damp proof effects.

Complete width and thickness specifications, low cost and easy installation.
