Description
Carbon Black N330 Rubber and Pigment Grade
Carbon Black N330 Rubber and Pigment Grade (CAS 1333-86-4, molecular formula C) is a coatings raw material used by paint, ink and adhesive formulators who need consistent dispersion, opacity and rheology from drum to drum. China Chemicals supplies it at 99% carbon in pack sizes from 1 kg through to 500 kg Pallet, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as Furnace Black, HAF Black, Pigment Black 7. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
Typical applications
- Reinforcing filler in tyre and technical rubber
- Black pigment in paint, ink and coating systems
- UV protection in polyethylene pipe and cable
- Conductive filler in antistatic compounds
- Toner and masterbatch manufacture
