The 60 mil EPDM pond liner from Qingdao Shuangshi New Material is an industrial-grade, vulcanized elastomer engineered specifically for critical water containment. With a 33% increase in mass over standard 45 mil liner options, the EPDM liner 60 mil provides superior hydrostatic pressure resistance and mechanical durability.
This 60 mil EPDM liner is designed for professional Koi ponds, large-scale water features, and complex landscaping applications where substrate irregularities and long-term structural integrity are paramount.

Performance Characteristics
Inert Molecular Structure (Fish-Safe): Our EPDM rubber pond liners are formulated without plasticizers or toxic stabilizers. The chemically inert nature ensures 100% compatibility with Koi fish, aquatic flora, and nitrifying bacteria systems.
Enhanced Puncture & Tear Resistance: The 1.5 mm vulcanized EPDM profile offers exceptional resistance to mechanical damage from root penetration, sharp aggregates, and substrate movement.
Dynamic Flexibility: With an elongation capacity of ≥300%, the membrane maintains consistent wall thickness while conforming to irregular pond contours and shelves.
Environmental Stability: Engineered for continuous immersion and 24/7 UV exposure. It maintains thermal stability across a temperature range of -45°C to 80°C without delamination or embrittlement.
Primary Application Scope
Professional Koi & Ornamental Ponds: High-thickness protection for high-value aquatic environments.
Large-Scale Landscaping Water Features: Reliable containment for artificial lakes, streams, and golf course hazards.
Commercial Water Reservoirs: Engineered to handle the hydrostatic loads of deep-water containment.
Natural Swimming Pools (NSPs): Sustainable, chemical-free waterproofing for eco-friendly swimming habitats.
