CRX™1444 carbon black is a member of a special family of very high surface area products specifically developed by Cabot for very high performance treads.

Cabot revolutionized the industry in the mid 1950’s when it patented the process of adding potassium salts in trace amounts to the reactor. These salts prohibited the formation of "structure," allowing for the first time, the manufacture of low structure carbon blacks.

This carbon black is a pelleted furnace black and is used in tire applications including carcass, tube and inner-liner compounds. The product is ideal in tire compounding in areas where good dynamic performance is needed, with minimal heat generation in flexing, and areas where high black loadings are desirable.

A cost-effective carbon black that provides improved flowability in rubber compounds for high-temperature injection-molded applications and high hardness extrusion profiles. SPHERON 4000's unique morphology significantly reduces the potential for mold fouling. This can improve productivity and lower cost by reducing the need for mold cleaning in NBR.

SPHERON 5000A is one of the carbon blacks from CABOT’s "A" grade family. The surface aspect of extruded automotive profile and window channels is very important today. Class "A" automotive surface applications demand a very low level of particles that could cause visible surface imperfections leading to rejects or ‘scrap’. In response to that market requirement, a family of carbon blacks appropriately identified by the suffix "A", was developed by Cabot to address carbon black related extruded surface imperfections.
