This product is manufactured using high-quality virgin high-density polyethylene resin as the base material, with the addition of additives such as carbon black, anti-aging agents, antioxidants, UV absorbers, and stabilizers, and is produced using a three-layer co-extrusion process.
The products are divided into two types: smooth high-density polyethylene geomembranes and textured high-density polyethylene geomembranes. The textured high-density polyethylene geomembranes are further subdivided into single-textured and double-textured
Applicable Standard: CJ/T 234-2006 "High-Density Polyethylene Geomembranes for Landfills"
