COST EFFECTIVE:
Austin Black is one of the most cost effective pigment and mineral fillers available. It has a specific gravity of 1.3. When compared to carbon blacks with a 1.8 specific gravity and other mineral fillers at 2.6 to 2.9 specific gravity, Austin Black can significantly reduce compound costs.

DISPERSABILITY:
Austin Black readily disperses in natural rubber, synthetic rubbers, and plastics, which reduces mixing time without causing agglomeration or sacrificing the dispersion of other ingredients. The 17% to 20% volatile matter in Austin Black contains inherent oils that act as an internal plasticizer and dispersing aid. It has been recommended that Austin Black be one of the first ingredients added to the compound mix to fully utilize this unique property.

PHYSICAL AND CHEMICAL PROPERTIES:
Austin Black has a platy structure, and a ph value of 7.0. Its chemical and ultraviolet resistance should enhance the properties of most rubber and plastic compounds. It will not absorb moisture and can improve air retention and moisture permeation properties in rubber compounds. These facts, plus excellent dielectric properties make Austin Black ideal for compounds requiring good dielectric
properties.

ATTRIBUTES OF 
AUSTIN BLACK IN RUBBER

• Combining Austin Black with HAF or FEF carbon blacks will produce better physical properties than thermal or SRF carbon blacks while significantly reducing compound costs.  

• Most rubber compounds can be diluted with 5 to 10 parts of Austin Black without impairing the physical properties. This may reduce the compound cost by 3 to 4%.  

• Austin Black functions as a processing aid. It facilitates air release from compounds which reduces bubble and blister problems.  

• Insulation compositions containing other standard fillers deteriorate in electrical properties following immersion in water. Compositions containing Austin Black make it ideal for companies requiring good electrical properties.  

• Addition of as little as 20 parts Austin Black will eliminate the disagreeable odor of a Di Cup cure system. 

• Austin Black will help minimize migration in a rubber to metal bonded product, and will significantly reduce staining of rubber compositions.
