The rough surface HDPE geomembrane material is composed of 97.5% high-quality polyethylene, 2.5% carbon black, trace antioxidant and heat stabilizer. The rough surface is the result of a special co-extrusion process, the process is a molding production, the most important characteristic rough surface HDPE geomembrane offer is that it can increase the stability of the slope material, from Ji-light delay Gan hoot imitation dec containing wet splashing and ultimately HDPE geomembrane can carry Kongyong Rong maximize product adapted to the characteristics of the laying of a steep slope in cost savings but also improve design capabilities.
