Environmental Protection Black HDPE Textured Geomembrane Sheet For Biofloc
HDPE Textured Geomembrane
Quick Detail:
Wanshengli Brand hdpe textured geomembrane is the impermeable synthetic membrane liner and geotechnical engineering materials which are widely used for solid waste containment, mining and water containment applications.
HDPE textured geomembrane with rough surface is a new type of anti-seepage material. Single rough surface and double rough surface increase friction coefficient and anti-skid function, which is more suitable for steep slope and vertical anti-seepage and providing engineering stability.
HDPE textured 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, which is widely used for fishpond, solid waste containment and water containment environment and mining environment. Anti-seepage HDPE geomembrana 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.
It has excellent temperature adaptability, weldability, tolerance and aging resistance, chemical corrosion resistance, environmental stress cracking resistance and anti pierce performance. Therefore, it is especially suitable for underground engineering, mining engineering, sewage and waste residue treatment plant as impermeable materials.
