This XM-PB08 grade is an industrial precipitated barium sulphate white powder for plastics, rubber, coatings and sealants, with paint also identified in its product name. Its 98–99% purity range and paired particle-size criteria make the enquiry specific to a defined sulfate grade rather than an unspecified white mineral.
Pair median size with the upper distribution
For XM-PB08, D50 is 0.5–0.7 microns and D97 is 1.8–2.5 microns. Read those values as different distribution criteria and agree the measurement method before comparing fine sulfate grades; neither range describes every particle or guarantees a finished coating result.
Separate composition from colour acceptance
The 98–99% purity range and 98–99% whiteness range describe different aspects of XM-PB08. A colour-sensitive formulation should set an assay requirement and a whiteness test separately, rather than treating matching percentages as one combined material property.
- For a polymer trial
- Identify the intended plastic or rubber matrix and its processing acceptance criteria.
- For coating or sealant development
- Agree the binder system, particle-size basis and required appearance tests for XM-PB08.
- For initial material evaluation
- Sampling is identified; confirm the representative grade and arrangements before requesting a trial portion.
Qualify the supplied powder in the actual system
A pH range of 7–8 adds another comparison criterion for this precipitated sulfate, provided the test method is defined. Current composition and safety documents, any required certification evidence and a representative formulation trial should establish whether the proposed XM-PB08 grade meets the project's requirements.
Keep the 0.5–0.7 micron median range, the 1.8–2.5 micron D97 range and the separate assay and colour targets together when specifying this particular XM-PB08 enquiry.
