XM-BA387 Natural Barium Sulphate Barite for Rubber and Brake-Pad Filler Evaluation, 94% Minimum Purity

XM-BA387 is an industrial natural-barium-sulphate white powder identified for rubber and brake-pad filler evaluation, with a minimum purity of 94%. Its D50 of 3 microns and D97 of 8 microns provide defined size criteria for a material enquiry.

Define the actual XM-BA387 filler role

A rubber-compound project and a brake-pad material project need their own formulation and acceptance requirements. Confirm the intended sulfate role and applicable qualification evidence before selection; the named filler direction does not establish friction, braking or finished-component performance.

Agree the powder and optical comparison methods

Use the D50 and D97 with their measured distribution and test method, and choose the actual whiteness grade within 92–98%. Oil absorption is 13–15 g/100g and pH is 7±0.5, each requiring an agreed method rather than serving as a finished-compound result.

Composition review

Confirm the minimum 94% assay and the 0.04% Fe2O3 criterion through current product-specific analysis.

Conditioning criteria

Volatile matter at 105°C is 0.20%, loss on ignition is 1.10% and water-soluble matter is 0.20%; agree the applicable procedures.

Physical basis

Confirm the method behind the specific-gravity entry and the actual natural-material route for the proposed grade.

Keep component approval tied to actual qualification

Request current technical and safety information for XM-BA387 before a representative material trial. The actual compound or component project should determine which processing and performance tests apply, rather than transferring a result from another rubber or coating system.

For this barite enquiry, connect the confirmed assay, particle criteria and physical methods to the intended filler task. Relevant formulation and component evidence should establish the actual material decision, with no braking or service-performance conclusion inferred from the sulfate name.
