The accepted chemical limits are the first useful comparison for a natural mineral filler. This industrial white barium sulphate powder has a declared 90% purity for paint, plastics and powder-coating evaluation, with further grade information needed before approval.
Screen the natural grade against the assay requirement
Request current chemical identification and analysis for the offered material. Compare the declared 90% with the buyer's actual acceptance limits, rather than treating a chemical name or natural designation as a complete purchase specification.
Define the particle and colour requirements
Ask for unit-defined particle distribution and a measured whiteness result with its method. Confirm any treatment information as part of that powder report, because white appearance does not establish a particular fineness, dispersion response or finished-product optical result.
- Agree the accepted chemistry and actual supplied grade.
- Review particle, colour and treatment measurements.
- Set the formulation trial around the intended application.
Choose the binder or polymer that matters
Paint and powder-coating enquiries should identify the actual binder and film-test criteria. Plastics enquiries should identify the polymer and processing requirements separately, without assuming that a result in one coating system establishes compatibility in another formulation.
Include the assay limits and intended material system with the technical enquiry. A confirmed grade specification and a relevant trial provide a practical basis for selecting the natural 90% powder without an assumed dispersion or performance guarantee.
