Particle selection is central to this industrial barium sulfate enquiry. The white BaSO4 powder has a stated purity range of 85%-88%, with six model options carrying different d50 upper limits for coating, ink and plastic formulation assessment.
Read each model's own d50 limit
The options below pair a named model with its stated limit. Keep that pairing intact when requesting a sample, and ask for the measurement method and full distribution rather than treating d50 as the largest particle present.
- NA4390: d50 ≤ 2.5μm.
- NA4387-3000: d50 ≤ 4.0μm.
- NA4387-2800: d50 ≤ 4.8μm.
- NA4387-2500: d50 ≤ 5.5μm.
- NA4386-1600: d50 ≤ 8.5μm.
- NA4386-600: d50 ≤ 23μm.
Separate a mesh label from a measured distribution
The 325-mesh and 1250-mesh designations need confirmation against the proposed material. They do not assign either mesh label to a particular model or replace its particle report. For a coating, ink or plastic trial, identify the formulation and agree which particle and appearance measurements matter before comparing candidate grades.
Give protection enquiries their own qualification
Radiation protection is an enquiry application, not a demonstrated shielding result for this powder. A protection project requires its own material specification, qualified design and relevant testing. Request the selected model's technical sheet, safety information and batch-linked assay, and confirm how its purity range applies to the offered grade before drawing any application conclusion.
