Calcium oxide CaO with stated purity of 90%-93% is the material for this plastic defoaming-masterbatch and rubber moisture-control enquiry. Three actual mesh choices allow a specific grade request, with its activity and process performance still to be established.
Select the actual mesh designation
The options are 400-600mesh, 800-1000mesh and 1250mesh. Request the selected grade's sieve standard and distribution report rather than assuming all powders within the overall span are equivalent. Confirm which sieve is used for its residue result.
Read the reported quality limits on their methods
Hydrochloric-acid-insoluble content is stated as ≤0.5%. Reported fineness residue is ≤5% on a sieve within the stated 400 to 1250 mesh range, with the grade-specific test basis to be confirmed. Whiteness is reported as 80, without a defined scale or method here.
- Grade characterization
- Match assay, sieve residue, particle distribution and optical method to the sample.
- Process characterization
- Request a relevant activity test and the intended-system qualification evidence.
Evaluate the moisture-control role in the intended system
Describe the polymer or rubber process and the acceptance requirements before assessing a representative material. Review matched technical and safety information and keep the proposed grade identifier with the test conditions. No moisture-absorption capacity, reaction recipe or universal defoaming result is established here. Retain the selected mesh specification and process evaluation together so a repeat enquiry refers to the actual material and application examined.
