Carbon black is one of the darkest and most finely divided materials known.  Chemically, carbon black is a colloidal form of elemental carbon consisting of 90 to 99 percent carbon.  Made in specially designed reactors operating at internal temperatures in the range of 2600° to 3600° F, different grades of carbon black can be produced with varying aggregate size and structure.  It is these differences that allow our blacks to be used in a variety of applications.  Sid Richardson Carbon & Energy Co. has over 30 different grades of carbon black available for use in rubber, plastics, inks, and various other applications.

Tire Blacks

Carbon black in tire applications can be divided into two basic categories: tread and carcass.  Tread grades are highly reinforcing and can be identified by ASTM numbers in the 100, 200, and 300 series.  These blacks provide improved tread wear of tires as well as traction, cut resistance, and sidewall abrasion resistance.

Carcass grades are semi-reinforcing and are identified by ASTM 500, 600, and 700 series designations.  In tire applications, these carbon blacks are used in the body of the tire where they impact ply strength, hysteresis and air retention.

In addition, several SR (specialty) grades have been developed for unique applications in tires, both carcass and tread.

Industrial Rubber Black

SRCE offers a wide range of both ASTM and SR (specialty) grades for industrial rubber applications.  Our blacks are used every day in some of the toughest quality applications that exist for industrial or mechanical good parts. Examples include automotive sealing systems, brake diaphragms, sheet roofing, lathe cut gaskets, molded parts, and extruded parts.

Special Applications

Several of our ASTM and SR (specialty) grades are used in many industrial applications including printing inks, plastics, paints, and batteries. We have ongoing efforts to develop new applications in the areas of fuel cells, coatings, industrial cables, and electronic chemicals.
