ASTM Grades

Rating Function & Compounding
N110 Gives maximum abrasion resistance, highest reinforcement and tensile. Used in off the road tire treads, tread rubber, bridge pads and conveyor belts.
N220 Provides excellent abrasion resistance, high tensile, good tear properties, moderate electrical conductivity. Used in truck and passenger tires, and mechanical goods.
N299 Provides abrasion resistance superior to N339, N375, N220 and comparable to N234. Used in truck and passenger tires, tread rubber, and mechanical goods.
N326 Low structure, high reinforcement, high tensile strength, very resistant to tear and chipping in natural rubber compounds. Used in mechanical goods, tire carcasses, belts, and off the road tread.
N330 Provides good abrasion resistance with high resilience, easy processing, and good tensile and tear properties. Wide range of applications in natural rubber and synthetic rubber compounds for both tires and mechanical goods.
N339 Provides superior wear and cut growth resistance vs. N347. Excellent wear and extrusion properties typical of improved process high structure blacks. Used in passenger treads, tread rubber, and mechanical goods.
N347 Used in NR, SR. Provides excellent processing characteristics and permits use of high oil loading with low die swell. Better hysteresis properties than improved treadwear versions. Used in treads, tread rubber and mechanical goods.
N351 Provides good abrasion resistance in the N330 range. High structure, high modulus black with easy processing characteristics. Excellent dynamic properties. Used in the tire tread and carcass compounds and mechanical goods.
N550 Imparts medium abrasion resistance, high strength, low shrinkage, and die swell. Provides fast, smooth extrusions and relatively high resilience. Used in tire carcasses, cushion gum, tubing, cable jacketing, plastic conduit compounds and in extruded goods requiring excellent dimensional stability.
N650 High structure, medium reinforcement gives low die swell, smooth extrusions, and easy processing plus economical compounding. Used in tire carcasses and sidewalls, cable jackets, inner tubes, and hoses.
N660 Moderately reinforcing grade. Excellent general purpose black. Provides good reinforcement, low heat generation, smooth processing to all elastomers. Used in tire carcass sidewalls and mechanical goods.
N762 Moderately reinforcing grade, gives high resilience and excellent dynamic properties, low hysteresis, high loadings obtainable. Used for extruded goods, belts and hoses, and molded goods. Also used in plastic color concentrates.
N772 Moderately reinforcing grade, gives high resilience and excellent dynamic properties, used in tire carcass and mechanical goods.
N774 Moderately reinforcing grade, gives high resilience and excellent dynamic properties, low hysteresis, and high loadings obtainable. Used in tire carcasses and sidewalls, extruded goods, belts, and hoses. Also used in plastics color concentrates.
