Industrial Barium Sulphate Coating Powder, 95% Whiteness for Plastic Formulation Evaluation

This industrial barium sulphate coating powder has a pure-white colour description and a 95% whiteness designation. For coating or plastic development, confirm the optical method and actual chemical assay separately before deciding whether the material meets the formulation's raw-material criteria.

Keep whiteness separate from purity

The 95% whiteness designation is an appearance criterion for this sulfate, not a confirmed chemical-purity percentage. Request a current assay with a clearly defined basis and unit, and compare the whiteness using the agreed method and reference relevant to the intended coating or plastic article.

Request the actual particle-size specification

A D50 comparison needs a numerical value, unit and measurement method for the offered powder. Obtain the full size distribution where the formulation requires it, rather than treating a particle-size term as a complete fineness specification or using the whiteness number as a size value.

Industrial identity

The material is identified as barium sulphate for coating and plastic evaluation.

Appearance evaluation

Pure white is a qualitative colour description that still needs a relevant optical acceptance test.

Supporting documents

Request confirmed chemical identity, composition and product-specific safety information for the offered material.

Qualify the powder in the chosen formulation

Use a representative coating or resin trial to establish the actual processing and appearance result. An industrial classification or a certification label does not itself prove applicable certification or finished-product performance, so obtain the current document with the relevant holder and scope where it is required.

For this sulfate enquiry, link the 95% whiteness designation to a defined optical test, while the independently confirmed assay and measured D50 criteria establish whether the proposed powder can meet the actual coating or plastic specification.
