Rubber-compound evaluation needs both chemical analysis and a defined fiber sample. XM-CS300 is an industrial white calcium sulfate whisker powder with an anhydrous designation, stated minimum purity of 98% and CaSO4 content above 98%. Its stated whiteness is at least 92%.
Obtain the XM-CS300 fiber specification
Request measured dimensions and the distribution of fiber shapes for the proposed sample. Confirm phase and hydration documentation associated with the anhydrous designation. A whisker name does not supply an aspect ratio or establish a reinforcing result in every rubber formulation.
Keep the physical constants on their own basis
The stated refractive index is 1.585 and pH is 6–7, each needing its relevant measurement conditions. A melting-point value of 1450°C is also given. That value does not define a suitable compounding temperature or the service limit of a finished rubber product.
Set the rubber comparison before processing
Identify the elastomer, recipe and processing conditions for the trial. Define which handling and finished-compound criteria will determine acceptance. Evaluate the actual sample through that system rather than assuming a loading ratio or a universal mechanical benefit.
Match the documents to each application
Plastic, coating, paint, paper and powder-coating uses are also named, but each requires its own qualification. Request current assay, physical-test methods and any applicable compliance documents with the sample. Keep those records connected to the fiber material actually tested before making the final selection.
