Improving Customers’ Formulas and Sustainability Since 1987

Austin Black 325 is a zero emissions filler that has been improving formulas with fewer CO2 emissions for more than 35 years. A dry, finely divided powder, it is manufactured by grinding high quality, sustainable bituminous coal. It is not burned, therefore it does not emit carbon dioxide. In comparison, every pound of carbon black that is produced emits an average of 2.4 pounds of CO2. Therefore, customers can achieve an immediate reduction in CO2 emissions by replacing a portion of the carbon black in existing formulas with Austin Black 325.

In addition to directly impacting carbon reduction initiatives, Austin Black 325 can fill more molds with fewer pounds of material, improve air retention, and help resolve carbon black supply chain issues.

On average per year, our customers

reduce CO2 emissions
by up to 1.4 million pounds

based on an average annual purchase of 616,802 pounds.

Fill more molds with fewer pounds of material.

Thanks to its low specific gravity, Austin Black 325 can fill up to three times as much volumetric space as other mineral fillers, creating more finished product at a significantly lower per pound volume cost. 

 

As one of the most cost-effective pigments and mineral fillers available, it has a specific gravity of 1.30. When compared to the specific gravity of carbon blacks at 1.80, and other mineral fillers at 2.60 to 2.90, Austin Black 325 helps manufacturers lower compound costs, which ultimately leads to increased profitability. 

Improve air retention.

Austin Black 325 has been shown to improve air retention by 21.6% in tire inner liner applications.

 

Read the results of a recent study by ACE Laboratories that evaluated the performance of Austin Black 325 in a butyl inner liner application. The platy structure of Austin Black 325 helps create an air barrier within rubber compounds to reduce air permeation and improve air retention.
