Function & Compounding
Specialty Grades:
SR155 High surface area, high tint tread black for truck or racing tires; provides excellent abrasion resistance.
SR301 N300 type black, medium OAN, soft pellet, low sieve residue; for ink, plastic, coloring applications.
SR303 N300 type black, low OAN, soft pellet, low sieve residue; for ink, plastic, coloring applications.
SR310 High structure version of N330 for increased modulus.
SR315 N300 type black, high OAN, soft pellet, low sieve residue; for ink, plastic, coloring applications.
SR401 N400 series black for synergistic properties.
SR450 Intermediate surface area, low structure black for ink applications.
SR511 Unpelletized N550 for ink, paint, coloring applications.
SR530 Low sieve residue N550 for plastic and rubber applications where surface defects cannot be tolerated.
SR630 Low sieve residue N650 for plastic and rubber applications where surface defects cannot be tolerated.
SR711 Unpelletized  N762 for extruded goods, belts and hoses, and molded goods. Also used in plastic color concentrates.
Sidcon 119 Developed as a cost effective conductive carbon black. SR119 imparts electrical conductivity to rubber and plastic products while also offering improved processability.
 
Sidcon 159 Developed as a highly conductive carbon black. SR159 imparts electrical conductivity to rubber and plastic products at low loading levels.
Sidcon 419 Sidcon 419 was developed as a static dissipative carbon black that features improved conductivity and processability over semi-reinforcing grades of carbon black.
