Profitability
The Science Behind the Savings

All test tubes contain 10 grams of the respective filler indicated.
Material weight, although the same (10 grams) fills different volumetric space.
In the case of Austin Black 325, its low specific gravity creates more finished product to lower total costs.
Our signature product – Austin Black 325
Volumes Cost Savings: Austin Black 325 vs. Clay and GCC
ACE Laboratories conducted research replacing soft clay and ground calcium carbonate with Austin Black 325 in EPDM rubber formulas.
AB325 has a specific gravity of 1.30, soft clay averages a gravity of 2.5, and ground calcium carbonate averages a specific gravity of 2.7. This reduction in weight per volume allows for less material usage when making the same number of products.
