In this latest webinar, Smithers experts, Dustin Jenkins and Keegan Moss will cover improved measurement techniques for carbon black qualification.
ASTM D3849 Overview
ASTM D3849 is the only recognized standard method for the digital measurement of carbon black particle size statistics via transmission electron microscopy. The method makes use of fractal geometry to derive particle size statistics for both aggregates and primary particles using only measured values of aggregate perimeter and area. Despite the sophistication of ASTM D3849, there has been discussion regarding its utility and reproducibility in the industry, especially with regards to smaller grades of carbon blacks. As a leader in third party testing within the rubber and tire industries, Smithers has recently developed an improved methodology based on ASTM D3849 that seeks to address these issues and improve identification of carbon black obtained from mixed rubber samples.
The agenda includes:
•ASTM D3849: A Brief Overview
•Method Development & Data Studies
•Improved Data Treatment
•Data Comparison: Smithers Method vs. Donnet et al.
•Modeling Bulk Properties
