Production Description:
HDPE geomembrane is made from 97.5% high density polyethylene (HDPE) and 2.5% Carbon black/anti-aging agent/anti-oxygen/UV absorbent/stabilizer and other accessory, Product is made of best quality high density polyethylene (HDPE) with specially formulated and original polyethylene resin, it 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.
HDPE anti-seepage geomembrane has single rough surface and double rough surface, it can increase friction coefficient and anti-skid function, which is more suitable for steep slope and vertical anti-seepage and provides engineering stability.
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 case, mining case, sewage and waste residue treatment plant as impermeable material.
Advanced equipment, imported model, 3 layer extrusion production method with all kinds of specification products, welcome to inquiry and visit our website.
