SP150 Conductive Carbon Black
Acetylene conductive carbon black. Oil absorption 220–270 ml/100g; iodine absorption 85±10 g/kg; resistivity ≤0.25 Ω·cm. TDS map: silicone, rubber, supercapacitors and related uses.
SP150 is an acetylene-process grade in our conductive carbon black family. On the family TDS, grades whose names start with SP are acetylene blacks; grades whose names start with a number are furnace conductive blacks. The same sheet describes acetylene grades as combining high purity and high conductivity with very low ash, metal-impurity and sulfur levels. CAS No. 1333-86-4 · H.S. Code 2803000000 · general chemical grade.
SP150 technical specifications
These values are taken from the DLcarb conductive and antistatic carbon black TDS (printed 3 August 2025). They are specification ranges, not results from a single production lot.

Note: figures above are TDS specification ranges for reference. Delivery specifications follow the technical agreement we confirm with you. Please validate the grade in your own formulation and process. Safety information sits in the SDS (EU REACH), not in the TDS table.
The TDS leaves the iron column blank on the SP150 row, so this page does not invent an Fe limit. Resistivity is published as ≤0.25 Ω·cm; heating loss and ash are each ≤0.50%.
Where the TDS application map places SP150
The second page of that TDS marks SP150 for the uses below. It does not place a mark on SP150 for lithium-ion, sodium-ion or solid-state batteries — those columns belong to the Li-suffixed acetylene rows, including SP250-Li.
- Cathode and anode slurries; dry batteries; lead-acid batteries; fuel cells; supercapacitors
- Specialty ceramics; metallurgical industry
- Conductive silicone and antistatic silicone; conductive rubber and antistatic rubber
- Antistatic floor coatings; antistatic flooring materials; antistatic leather; antistatic coatings
- Heat-tracing cables; thermally conductive materials
The map does not mark SP150 for conductive plastics, antistatic plastics, conductive coatings, conductive inks or extra-high-voltage cable shielding compounds. If those are your target systems, say so when you inquire and we will point you to the rows that are actually checked. A broader comparison sits in our conductive carbon black selection guide.
Documents and storage
Alongside the TDS we publish an EU REACH SDS for carbon black (CAS 1333-86-4) and three SGS reports dated 26 June 2026 on a submitted carbon black sample: REACH Candidate List SVHC screening (253 substances, results ≤0.1% w/w, plus one potential SVHC also ≤0.1% w/w); EU RoHS Directive (EU) 2015/863 amending Annex II to 2011/65/EU (Pass); and halogen testing to IEC 62321-3-2:2020 (fluorine, chlorine, bromine and iodine reported ND on that sample; MDL 20 mg/kg for F and 50 mg/kg for Cl, Br and I). Those reports describe the submitted sample — they are not a substitute for the grade TDS or a lot COA. The SDS service summary lists selected DLcarb model numbers and does not name SP150 separately; treat the SDS as the carbon-black document for this chemistry and ask us if your file needs a model-level confirmation.

The TDS storage note is the same across these sheets: keep the material in a cool, dry, well-ventilated warehouse; protect it from moisture; guard against dust inhalation and skin contact; store it apart from strong oxidants and do not mix-store. For classification and safe handling, follow the SDS rather than the short TDS footnote. We do not publish MOQ or Incoterms on this page; those belong in the quotation.
