Paint, ink and plastic enquiries need their own formulation acceptance criteria. This industrial natural barium sulfate BaSO4 barite is described as white fine powder with stated BaSO4 ≥85.0%, with rubber and powder coating also named as material-assessment targets.
Define the proposed formulation before comparing grades
Identify the actual system and agree representative evaluation conditions. Keep the criteria relevant to that application rather than assuming a result in a paint, ink or plastic formulation will transfer to another use. Retain the proposed material reference with the assessment brief.
Compare actual composition and measured grading
Request current BaSO4 and relevant impurity analysis for the offered sample. The minimum content is a threshold rather than its exact composition. Obtain particle-distribution or sieve reports with their method; fine or superfine wording does not define numerical size or a mesh fraction.
Set optical and additional-property questions separately
Ask for an optical report if numerical whiteness matters to the formulation. White appearance is descriptive, while density and surface treatment each need separate supporting information where relevant to selection.
Keep documentation with the actual evaluation
Confirm identification in matched technical, analysis and safety documents and evaluate the proposed grade against the agreed criteria. Qualify any rubber or powder-coating role independently. Keep the sample identity, conditions and observations available for later enquiries. Neither the natural-barite name nor the minimum content and superfine designation establishes verified dispersion, gloss, opacity, loading ratio or a universal finished-formulation result.
