Carbon loading, carrier system, ash, melt flow and moisture for all twelve standard grades, in one table. Each grade has its own data sheet; the SDS and the batch certificate of analysis are issued with the shipment.
Measured in our own QC laboratory. Print this page or save it as PDF for your file; the contractual numbers are confirmed against your order and restated on the batch CoA.

Density <2.0 g/cm³ on all PE-based grades (HP wax grade measured 1.237 g/cm³). Recommended let-down 1–3% across the range. Packaging 25 kg KP or PE bags, 20 bags per pallet. HS code 32064900. Loading port Shenzhen, China. Carbon black type (N220 or N330) per grade — see below.
| Grade data sheet (TDS) | One page per grade, with the values above plus recommended let-down, processing window and packaging. Sent with the quotation, or on its own if you are still screening. |
|---|---|
| Safety data sheet (SDS) | Issued with the quotation, in the language and format your country requires. Carbon black masterbatch is not classified as a dangerous good for transport, but the SDS is still a required document for your file and for your own customers. |
| Certificate of analysis (CoA) | Per lot, per shipment. States what that batch actually measured — including the filter-pressure result with mesh size and test polymer — not a reprint of the typical values above. |
| Certificates | ISO 9001 / 14001 / 45001, supplied with certificate number and issuing body so you can check them yourself. 22 SGS test reports are downloadable as original PDFs. |
| Origin and compliance | Commercial invoice, packing list, CoA, certificate of origin and a signed origin and forced-labour statement travel together as one document set. |
On the numbers above: they are typical in-house QC reference figures, not contractual limits. The contractual specification is what we confirm against your order, and it is the CoA — not this page — that states what your lot measured.
For pipe, cable and pressure applications, dispersion is the specification that matters ahead of jetness. An agglomerate in a pressure pipe wall is a stress concentrator, and that is where a slow crack starts.
“10% carbon black” tells a buyer almost nothing on its own. Which carbon black decides UV life, jetness, how much shear the compound needs, and where the filter pressure lands. We run two oil-furnace blacks classified under ASTM D1765 — N220 and N330 — and the type used in a given grade is named on that grade’s data sheet and on the lot certificate.
| Type | Class | Typical particle size | What it buys you | What it costs you |
|---|---|---|---|---|
| N220 | ISAF — intermediate super abrasion furnace | about 20–25 nm | More jetness per point of loading and a denser UV screen at the same dose. The finer particle size sits inside the particle-size window that pressure-pipe standards write for pipe-grade carbon black. | Harder to disperse. It wants more shear, and a slack compounding regime shows up immediately as higher filter pressure. |
| N330 | HAF — high abrasion furnace | about 28–36 nm | Disperses more easily, runs to a lower filter pressure, and costs less per kilo. The normal choice where jetness is not the specification and the part is not a pressure wall. | Less jetness at equal loading — you dose slightly more to reach the same black. |
Structure is measured by DBP absorption (ASTM D2414) and reported with the batch. We name the carbon black per grade rather than per company, because the choice follows what the part has to survive: an exposed PE100 pressure wall and a black injection-moulded appliance housing do not want the same carbon black. If your specification fixes the carbon black type — pipe and geomembrane specifications often do — tell us and we quote to it.
Where each grade sits: carbon black type per grade is stated on the grade’s own data sheet and on the lot CoA, not left for you to infer. Ask for the TDS of the grades you are screening and you will see it there.
No. They are typical in-house QC reference figures. The contractual specification is what we confirm against your order, and the batch certificate of analysis states what that lot actually measured.
Yes. We issue the SDS with the quotation, in the language and format your country requires. Carbon black masterbatch is not classified as dangerous goods for transport, but an SDS is still a required document for your file and for your own downstream customers.
Filter-pressure test for release, with the mesh size and test polymer stated on the certificate of analysis. Where you need a microscopic dispersion rating, we report to ISO 18553 at the let-down you intend to run.
We run two oil-furnace blacks classified under ASTM D1765: N220 (ISAF, about 20-25 nm) and N330 (HAF, about 28-36 nm). N220 gives more jetness per point of loading and a denser UV screen; N330 disperses more easily and runs to a lower filter pressure. Which one a given grade uses is stated on that grade’s data sheet and on the lot certificate of analysis. If your specification fixes the carbon black type, tell us and we quote to it.
Tell us which grades you are screening and what you run them on. We send the TDS and SDS the same working day, with a firm factory quote if you want one.
