HDPE geosynthetic Liner
1. Resistant to decay and aging, resistant to acid, alkali and soil corrosion, resistant to ultraviolet rays. The performance is stable for long-term outdoor use, suitable for various harsh geotechnical environments.
2. Excellent water-proofing performance, with a dense molecular structure without pores, effectively blocking water and seepage. The waterproofing effect is far superior to that of traditional geotechnical materials.
3. Excellent tensile and tear resistance, with excellent physical and mechanical properties. It can adapt to foundation settlement and soil deformation. It is not prone to damage after construction and laying, and has strong durability.
Chapter 1: Introduction
HDPE geosynthetic liner, made from high-density polyethylene resin with anti-UV agents and antioxidants, is a high-performance impermeable geosynthetic material produced by extrusion and calendering. It features excellent impermeability, corrosion resistance, mechanical strength and durability. Widely used in environmental protection, water conservancy, transportation and agriculture, it is a core material for anti-seepage and isolation projects globally. This article introduces its specifications, uses, prices, international applications, parameters, enterprise advantages and future development in 7 chapters, providing a concise and comprehensive reference.
