ASTM BLACKS

APPLICATIONS: Tires, hoses, belts, pipes, MRG & more

N110

 

Pellet

​

Gives maximum abrasion resistance, highest reinforcement and tensile. Used in off the road tire treads, tread rubber, bridge pads and conveyor belts.

N120

 

Pellet

​

Versatile high surface area black for demanding tread applications and balance of other properties.

N121

 

Pellet

​

Provides excellent abrasion resistance. Used in truck and passenger tire treads.

N134

 

Pellet

​

Provides superior abrasion resistance. Used in truck and passenger tire treads.

N220

 

Pellet

​

Provides excellent abrasion resistance, high tensile, good tear properties, and moderate electrical conductivity. Used in truck and passenger tires, and mechanical goods.

N231

 

Pellet

​

Low structure, high abrasion resistance, used mainly in tires where resistance to tear is important.

N234

 

Pellet

​

Provides superior abrasion resistance vs. N220. Excellent wear and extrusion properties typical of improved process high-structure blacks. Used in all elastomers, especially SBR/BR blends for treads and tread rubber.

N299

 

Pellet

​

Provides abrasion resistance superior to N220, N339, N375, and comparable to N234. Used in truck and passenger tires, tread rubber, and mechanical goods.

N326

 

Pellet

​

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

 

Pellet

​

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

 

Pellet

​

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

 

Pellet

​

Used in NR and SR polymers. 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

 

Pellet

​

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.

N358

 

Pellet

​

Extra high structure. This can accommodate more oil than normal for equivalent modulus and hardness. Used in tire treads, tread rubber, and mechanical goods.

N550

 

Pellet

​

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

 

Pellet

​

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.

N772

 

Pellet

​

Moderately reinforcing grade, gives high resilience and excellent dynamic properties, used in tire carcass and mechanical goods.

N660

 

Pellet

​

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

 

Pellet

​

Moderately reinforcing grade, gives high resilience and excellent dynamic properties, low hysteresis, and high loadings obtainable. Used for extruded goods, belts and hoses, and molded goods. Also used in plastic color concentrates.

N774

 

Pellet

​

Moderately reinforcing grade, gives high resilience and excellent dynamic properties, used in tire carcass and mechanical goods.
