HDPE geomembrane (also known as waterproofing membrane), thickness ranging from 0.2mm to 3.0mm; above 0.8mm thickness, it's referred to as a waterproofing board. It's a waterproof and barrier material made primarily from high-quality polyethylene raw resin. The main component is 97.5% high-density polyethylene, with approximately 2.5% of carbon black, anti-aging agents, antioxidants, UV absorbers, and stabilizers as auxiliary materials. It boasts strong waterproof and isolation properties.
