A rubber-compound enquiry should distinguish a mineral powder input from a finished carrier-based product. XM-H500 is a talcum-designated powder with a 1250-mesh description, stated particle size of 3.5 μm and whiteness of 90%. Rubber compounds and filler masterbatch are named application directions.
Clarify the particle measurement for XM-H500
Ask which statistic and analytical method support the stated 3.5 μm size. Obtain the complete distribution before comparing the powder with another mineral. The value should not be relabelled as D50 or D97 without the relevant report, and the model name does not define a mesh grade.
Review the oxide and moisture requirements
The stated composition includes SiO2 at 50–55%, MgO at 30–32%, Al2O3 at 1.0% and Fe2O3 at 0.3%. Moisture is given as 0.5% maximum. Request current analysis and the test methods needed by the intended compound before accepting the material.
Define the actual rubber comparison
Name the elastomer, processing route and properties that determine trial acceptance. Evaluate the selected powder through that formulation rather than assuming a carrier resin, finished pellet specification or universal addition rate. Review oil absorption using its own method and the project's material requirements.
Keep the sample identity and result together
Obtain grade-specific identity documents with the current analytical report. Record the powder selection, processing conditions and compound results in the same trial record. This connects the XM-H500 enquiry with evidence from the actual rubber system under consideration.
