UV Resistant HDPE Geomembrane Liner Carbon Black 2.0-3.0% 4000h Outdoor Exposure for Dam Reservoir Pond Lining

UV Resistant HDPE Geomembrane with Carbon Black 2.0-3.0%

Formulated with 2.0-3.0% carbon black content, this HDPE geomembrane offers exceptional UV resistance exceeding 4000 hours of accelerated weathering testing. The advanced UV stabilization package ensures long-term durability for exposed applications including reservoir liners, dam facings, and open pond systems.

Weathering Performance

• Carbon black content: 2.0-3.0% for optimal UV absorption
• UV resistance: ≥4000h (ASTM G154/G155)
• Retains ≥80% of original tensile strength after 4000h UV exposure
• Ozone resistant for atmospheric exposure
• Oxidation induction time (OIT): ≥100 min standard, ≥400 min high-pressure

Ideal Applications

Exposed reservoir and dam liners, irrigation canal lining, decorative pond and lake liners, exposed landfill cap covers, solar evaporation ponds, and aquaculture ponds with UV exposure.
