How are your composite geomembranes manufactured? Does their peel strength meet national standards?
We utilize advanced thermal calendaring technology to laminate geotextiles and geomembranes. Unlike simple glue bonding, our heat-bonding process ensures a molecular-level integration between the layers.
Our composite geomembranes are engineered to exceed national and international standards (such as GB/T 17642). We maintain a peel strength ≥ 6N/cm (or higher depending on specific project requirements), ensuring that the layers will not delaminate even under high hydraulic pressure or during steep-slope construction.
What are the carbon black content and dispersion characteristics of the geomembrane?
This is a critical technical factor for exposed applications. Our geomembranes are formulated with a carbon black content ranging from 2.0% to 3.0%, which is the optimal window recommended by the GRI-GM13 standard for maximizing UV protection without compromising mechanical properties.
Regarding dispersion, we utilize advanced high-shear mixing technology to ensure that the carbon black is uniformly distributed throughout the polymer matrix. We categorize our carbon black dispersion according to the Category 1 or 2 rating (no large agglomerates or streaks), which guarantees that every square inch of the liner is shielded from photo-oxidation, effectively extending the service life of the project to over 50 years in typical buried or exposed conditions.
