Industrial carbon black grades

The American Society for Testing and Materials has classified these ASTM designation based on their manufacturing process, particle size, surface area, aggregate structure, abrasion resistance, and extrusion.

ASTM designation	Particlesize (nm)	Surfacearea (m2/g)	Applications
N110	15-18	124-130	High reinforcement. Used in tire products with high abrasion resistance.
N134	20-25	145	High reinforcement. Premium tread for passenger, bus, and truck tires.
N220	20-25	112-115	High reinforcement, tear strength, abrasion resistance. Tread for trucks and passenger tires.
N234	24-33	125	High reinforcement. Has many applications, like tread for trucks.
N330	28-36	76-80	Medium-high reinforcement, good flex and wear properties. Tread, carcass, and sidewall compounds for bicycle, passenger, and truck tires and rubber goods.
N339	28-36	95	Medium-high reinforcement. Passenger tire treads, body compounds for tires, conveyor belts, and motor mounts.
N375	36-38	91
N550	39-55	39-41	Medium-high reinforcement and smooth extrusion. Used in inner liners, carcass, and sidewalls for passenger tires, rubber goods, hose, and extruded products.
N660	56-70	34-36	Medium reinforcement, good flex, and fatigue resistance. Used in inner liners, sidewalls, sealing rings, cable jackets for tires, and rubber molding and extruded goods.
N770	71-96	31-32	Semi-reinforcing. Inner liners for tires and rubber goods.
N880	180-200	17-20	Low reinforcement. Used for non-tire rubber and plastic products.
N990	250-350	7-9	Low reinforcement, hardness, and tensile strength; high loading capacity and elongation. Used for tire inner liners and rubber and plastic products, like wire insulation, footwear, belts, hose, etc.
