Production Description:
Our anti-seepage HDPE geomembrane is widely used for fish pond, solid waste containment and water containment environment and mining environment. Geomembrane is made of best quality high density polyethylene (HDPE) with specially formulated and original polyethylene resin, combined with specified quantity carbon black, antioxidant, anti-aging agent and UV resistance components, which contributes to its excellent resistance to UV radiation and being suitable for different conditions.
Our Anti-seepage HDPE geomembrana is manufactured via triple co-extrusion technique by the most advanced automatic equipment. All the productions are manufactured according to US GRI standards and ASTM, complete specifications with superior quality. The width can reach 8m. Anti-seepage HDPE geomembrane IS far more cost effective, environmentally safe, excellent durable, chemically resistant, fast deployment and easy transportation than traditional concrete, asphalt and compacted clay.
Product has excellent temperature adaptability, weldability, tolerance and aging resistance, chemical corrosion resistance, environmental stress cracking resistance and anti pierce performance. It's especially suitable for underground engineering, mining engineering, sewage and waste residue treatment plant as impermeable material.
Size and color can be customized, normally is black and white. Other special color has quantity requiremets.
