Raw Material & Manufacturing Process

• Uses top-grade virgin geomembrane resins (domestic and international) to ensure the product’s base performance.
• Added with functional additives: carbon black masterbatch (for UV protection), anti-aging agents, antioxidants, UV absorbers, and stabilizers.
• Manufactured through blow molding (for large-width sheets) or calendering (for precise thickness control) processes.

Key Performance Features

• Extremely low permeability coefficient, meeting strict impermeability requirements for environmental protection projects.
• High tensile strength and elongation at break, adapting to ground settlement without cracking.
• Good weather resistance: Resists UV radiation, high/low temperatures, and oxidation, ensuring long service life (10+ years in outdoor use).

Typical Application Scenarios

• Waste management: Landfills, sewage treatment plants, and hazardous waste disposal sites for leakage prevention.
• Water conservancy: Reservoirs, channels, and irrigation systems to reduce water seepage loss.
• Underground engineering: Subway stations, basement foundations, and tunnel linings for waterproofing.
• Landscape and agriculture: Artificial lakes, golf course water features, and seawater/freshwater aquaculture ponds.

Product Specifications

• Thickness: 0.3mm ~ 3.0mm
• Width: 1.0m ~ 9.0m
• Roll length: 30m ~ 100m (or customized per user requirements)
