Carbon Black N550 – Turkey & UAE Supplier

Carbon black N550 is a soft-grade reinforcing filler developed to enhance the durability and flexibility of rubber compounds and because of its medium structure and surface area, it delivers the perfect balance between elasticity and strength. In fact, many manufacturers rely on it to improve product performance without increasing stiffness.

Although other grades offer higher reinforcement, they also raise hardness. Therefore, this grade becomes essential when flexibility and fatigue resistance are needed together. Moreover, its low heat buildup ensures energy efficiency during processing.

Since carbon black N550 disperses easily, it works well in both extrusion and molding operations. Furthermore, it helps reduce mixing time and improves processing flow.

Key Features

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 this grade 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. Carbonblack 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.
