- HDPE (High-Density Polyethylene): Offers superior tensile strength (20-40 MPa), excellent UV and chemical resistance, and is ideal for large ponds or aquaculture applications requiring durability and minimal maintenance.- LDPE (Low-Density Polyethylene): Provides greater flexibility, making it easier to install in ponds with irregular shapes. It's cost-effective and suitable for smaller or less demanding applications.- Installation: Both materials can be welded using heat or extrusion methods to create seamless, leak-proof liners. HDPE is preferred for large-scale projects like fish farms and irrigation ponds, while LDPE is suitable for garden ponds and small water features.
