Made at our plant in Huizhou since 2010. We compound black masterbatch for water, gas and corrugated pipe and for cable jackets — high carbon loading for weather resistance and a long, stable life underground.
Buried pipe and cable live outdoors for decades. The masterbatch has to hold color and protect the polymer from UV — lot after lot, year after year.
| Carrier resin | PE / HDPE / LLDPE (other carriers on request) |
|---|---|
| Carbon black content | 35 – 50% (UV-protection grade for outdoor pipe) |
| UV / weather resistance | High carbon loading for long-term outdoor stability |
| Dispersion | ≤ 3 on filter-pressure test — no weak spots, no streaks |
| Melt flow (MFR) | Matched to your pipe / jacket extrusion line |
| Certifications | ISO 9001 / 14001 / 45001 |
Send your pipe standard (e.g. PE80 / PE100) and wall / process — we match a grade to it.
High carbon loading protects the pipe and jacket from sunlight so color and properties hold over years of service.
High dispersion means no streaks or gels that cause weak points or line rejects on your extruder.
No trading-company layer. A firm factory quote and a faster answer — the margin stays in your cost.
Run a trial lot on your own line before you commit. We keep your spec confidential.
Typical pipe and cable applications our black masterbatch is compounded for:
Pressure pipe black for PE80 / PE100 systems, buried and exposed runs.
UV-stable black for power and comms cable sheathing.
Stable black for double-wall and drainage pipe.
Drip, irrigation and conduit pipe where weather resistance matters.
For outdoor and exposed pipe we supply high carbon-loading, UV-stable grades. Tell us the exposure and service life you need and we'll propose the loading.
We tune carrier, carbon loading and MFR to your pipe grade and extrusion line. Share the standard and wall thickness and we'll match a starting grade plus a sample.
We support trial and small batches, not just full containers. Tell us quantity and we'll quote both a sample and a production lot.
Typically 5–10 days to most markets, packed with your let-down guidance so your line can run it directly.
Tell us your pipe grade, carrier and quantity. We reply with a firm factory quote and a sample — no obligation.
