If you’re looking for a rubber-grade filler that offers flexibility, smooth processing, and cost efficiency, carbon black N660 is the answer. Although many rubber components require reinforcement, not all of them need stiffness. That’s why this soft-grade furnace black is ideal for a wide range of non-tread applications.
In fact, carbon black N660 offers a perfect balance of performance and economy. Moreover, it helps rubber compounds maintain shape and function under repeated stress.
Carbon black N660 is a soft reinforcing filler with a large particle size and low structure. Therefore, it produces rubber compounds with high elasticity and low heat buildup. Additionally, it provides good aging resistance and exceptional dispersion.

ToggleTechnical Properties:
Iodine Adsorption: ~36 mg/g
DBP Absorption: ~102 cc/100g
Structure: Low
Tint Strength: Low
Reinforcement Level: Soft
Processability: Excellent
Because of these features, N660 is especially useful in products that must flex repeatedly without breaking down.
1. Tire Sidewalls
Tire sidewalls experience continuous bending. Since N660 improves fatigue resistance, it prevents sidewall cracking and maintains structural integrity.
2. Inner Liners and Tubes
Inner liners and tubes must withstand internal pressure. Fortunately, this grade reduces heat buildup and enhances air retention. As a result, tires and tubes remain safe under various driving conditions.
3. Rubber Hoses and Gaskets
Automotive and industrial hoses need flexibility and thermal stability and because carbon black N660 maintains elasticity under heat and movement, it works well in rubber hoses, seals, and engine gaskets.
4. Rubber Mats and Shoe Soles
Rubber mats and shoe soles benefit from the softness and durability of this grade. Moreover, its low reinforcement level ensures comfort while still resisting wear.
Carbon black N660 is preferred globally due to its unique properties. Let’s explore its advantages:
Excellent Flexibility – Ideal for bending applications
Low Heat Generation – Extends rubber life under pressure
Fast Dispersion – Saves time during mixing
Aging Resistance – Increases service life
Cost Efficiency – Reduces overall production cost
Smooth Processing – Allows easy flow in molds and extruders
Low Shrinkage – Maintains rubber shape over time
Versatile Compatibility – Blends with NR and SBR seamlessly
Because of these reasons, N660 is used across multiple industries.
Although many grades exist, carbon black N660 remains in high demand due to its flexible nature. In Asia, it is used in tire sidewalls and liners. Meanwhile, in Europe, the material appears in hoses, bushings, and molded components. Furthermore, North American and Middle Eastern markets value it for cost-efficient rubber production.
