XM-388 Industrial Barium Sulphate White Powder, 98% Purity for Black-Rubber Material Evaluation

XM-388 is an industrial barium sulphate white powder with 98% purity. Its black-rubber enquiry context concerns the formulation in which the mineral may be evaluated, so confirm the actual compound and colour requirements rather than treating the raw powder as a black material.

Separate powder appearance from the rubber target

The supplied XM-388 material is white powder, while black rubber is a proposed application context. Define the elastomer, pigment system and required appearance tests before judging the sulfate's suitability; a low-whiteness description does not establish the colour or properties of every finished rubber compound.

Define fineness before using a nano description

A particle-size comparison for XM-388 needs an explicit unit, measurement method and distribution specification. Request those grade details before interpreting a nano-powder term or comparing the material with a sulfate defined by a measured micron-scale D50 or D97.

Composition criterion

The stated 98% purity needs a current product-specific analysis for the intended specification.

Physical-test basis

Confirm the scale and method for whiteness and the units and conditions of absorption measurements.

pH comparison

The 7±0.5 pH range is a criterion to compare using an agreed preparation.

Qualify the proposed industrial use

Plastic, coating, printing and battery-material directions are identified for XM-388, each requiring appropriate composition and process acceptance criteria. A black-rubber trial needs its own evidence, with current safety documents and any required certification proof reviewed before approval; an industrial-use label does not establish a performance guarantee.

For XM-388, build the material request around confirmed assay, particle-test units and the actual black-rubber acceptance criteria, allowing the compound trial to determine whether this sulfate candidate meets the project.
