Carbon Black N550 – Turkey & UAE Supplier

Carbon Black N550 loaded in jumbo bags inside shipping containers – Basekim shipment.

Carbon black N550 is a medium-reinforcing, soft-grade carbon black widely used in rubber products that need flexibility, durability, and low heat buildup. Manufacturers choose this grade because it delivers a balanced combination of strength and elasticity without making rubber too hard. With its medium structure and moderate surface area, carbon black N550 improves abrasion resistance, enhances fatigue life, and maintains smooth processing behavior. It disperses easily in rubber compounds, shortens mixing time, and supports stable extrusion and molding. As a result, it is ideal for applications such as hoses, belts, seals, gaskets, and general-purpose rubber goods where long service life and flexible performance matter.

Key Features Carbon Black N550

Because of its moderate structure and specific properties, this grade remains a trusted solution for multiple industrial products. Here are some important technical values:

  • Iodine Adsorption Number: ~43 mg/g

  • DBP Absorption: ~121 cc/100g

  • Structure Level: Medium

  • Tint Strength: Low

  • Heat Build-up: Minimal

  • Elastic Recovery: High

  • Processing Behavior: Excellent

Although Medium reinforcing carbon black is classified as soft, it offers noticeable reinforcement in finished products. Hence, it supports designs that demand flexibility under mechanical stress.

Why Choose Carbon Black N550?

In rubber compounding, you often need a filler that reinforces without making the product brittle. Carbon black N550 does exactly that. Since it improves tensile strength and flexibility together, it supports consistent performance over time.

Additionally, it reduces internal heat generation during dynamic use. As a result, products maintain their structure even under frequent movement. This makes it an excellent choice for sidewalls, belts, gaskets, and other rubber components.

Even though it has a lower tint strength than harder grades, it delivers a deep black color. Because of this, it remains visually consistent in finished goods.

Common Applications

Carbon black N550 is used in applications where balance is essential. As such, it appears in:

  • Passenger car tire sidewalls

  • Molded rubber parts

  • Industrial hoses

  • Footwear components

  • Gaskets and seals

  • Shock-absorbing elements

  • Conveyor belts

  • General-purpose rubber goods

Since it resists cracking and deformation, it extends the life of rubber products. Therefore, it is preferred in both automotive and general industry sectors.

Because of this balance, carbon black N550 is often selected when both strength and processing ease are required.

It has higher structure and reinforcement, making it better for semi-flexible products that need more strength.

While it is mainly used for black compounds, it can be modified for limited color-sensitive applications.

Actually, it helps reduce energy use during mixing and curing, which may lower overall costs.
