Made at our plant in Huizhou since 2010. We compound geomembrane black to the carbon content and dispersion level the liner standards call for — because on a lining job, a speck can turn into a leak path.
Geomembrane standards are unusually explicit about carbon black: content, dispersion and even the particle type. We build the grade around those numbers rather than around a shade of black.
| Carrier resin | HDPE (LLDPE / LDPE blend on request) |
|---|---|
| Carbon black content | Set to the level your liner standard requires, commonly in the low-percent range at final film |
| Dispersion | Tight and repeatable — carbon agglomerates are leak-path starters |
| Melt flow (MFR) | Matched to your flat-die or blown liner extrusion |
| Ash / screen pack | Controlled for long continuous runs without screen changes |
| Certifications | ISO 9001 / 14001 / 45001 |
Send us the standard your liner has to meet and your final thickness — we will confirm the grade and send a sample for your own testing.
We set carbon content and dispersion to the number your liner spec calls for, not to a visual match.
Dispersed carbon means fewer inclusions, which is what weld and leak testing is really looking for.
No trading-company layer. A firm factory quote and a faster, more technical answer.
Run a trial on your own line and test it before you commit. We keep your spec confidential.
Typical liner applications our black masterbatch is compounded for:
Aquaculture, irrigation and decorative ponds exposed to sunlight.
Bottom liners and closure caps for municipal and industrial sites.
Large-area pads where long outdoor life matters most.
Water conveyance and containment linings.
Yes. Tell us which standard the liner has to comply with and the final film thickness, and we will set the carbon content and let-down to hit it. We will say so plainly if we cannot meet a clause.
Through the compounding route, filter-pressure testing and lot records. Carbon agglomerates are the main reason liner welds and leak tests fail, so this is the parameter we watch closest.
Yes. Trial lots start at 1 ton per specification. Liner producers usually run a trial, test it against their own specification, then place the production order.
Typically 5–10 days to most markets, with the lot record and test data your QA team will ask for.
Tell us what you are running and how much you need. We reply with a firm factory quote and a sample — no obligation.
