The 1500 mesh option is the specific starting point for this heavy calcium carbonate plastics enquiry. The material is described as industrial white powder with stated purity of 96%, while the appropriate polymer use must be established through a defined qualification.
Ask whether the fineness fits the actual plastic
Name the polymer, intended article and properties that the assessment must address. A mesh designation alone cannot determine the ideal filler for that combination. Request the sieve standard and particle distribution so a comparison concerns measured material characteristics rather than a general fine-powder description.
Characterize the powder before judging dispersion
Obtain treatment information and clarify whether the proposed grade has a defined surface modification. Review its technical and safety documents alongside the current assay. The white appearance does not supply a numerical whiteness result, and stated purity does not establish dispersion in the intended resin.
Define an equivalent comparison
Keep the material identifiers and evaluation methods with the formulation record. If another filler is considered, confirm that its particle and treatment descriptions are understood on their own basis.
Keep the compound result tied to the sample
Assess a representative sample under agreed processing and acceptance conditions. No universal loading ratio, ideal mesh selection or finished-plastic improvement is established here. Record the tested powder specification and the relevant compound observations together. This gives a repeat enquiry a clear technical reference and helps distinguish a changed application requirement from a change in the calcium carbonate being proposed.
