301 identifies this industrial calcium carbonate white powder for rubber-reinforcement enquiries. Stated purity is 95%-99%, with tire and shoe-sole formulations named as intended assessment areas rather than demonstrated finished-product qualifications.
Turn reinforcement into a defined test question
Describe the elastomer system and the properties that the compound evaluation must address. Tensile behaviour and wear response need their own methods and acceptance criteria. Neither a reinforcement application name nor the powder's stated purity establishes an improvement in either property.
Confirm what active and nano mean for model 301
Request the particle-distribution report and the relevant measurement basis for the actual proposed powder. Obtain a description of any activation or surface treatment, including its confirmed scope. The designations do not supply a particular particle dimension or identify a surface chemistry on their own.
- Material evidence
- Matched assay, particle data, treatment information and safety documentation.
- Compound evidence
- Defined elastomer, formulation conditions and tensile or wear evaluation.
Keep the tire or sole assessment within its scope
Review the technical information before assessing a representative sample in the intended rubber system. Record the material identifier and test conditions with the results, and judge any proposed benefit against the agreed comparison. No loading ratio, finished-article approval or universal performance gain is established here. Retain the tested 301 specification and qualification record so a repeat enquiry refers to the powder and formulation actually evaluated, with any changed requirements clearly identified.
