Heavy Aromatic

Description

What Is Heavy Aromatic and What Are Its Applications?
Producer: Nouri Petrochemical Company

Heavy Aromatic is a high-value industrial cut derived from refinery and petrochemical aromatic streams. Due to its very high aromatic content, suitable density, and controlled distillation range, it is widely used in downstream industries. It typically consists of C9 and C10 aromatics and, compared to light aromatics, has a higher boiling point and greater stability.

The primary consumption focus of this aromatic cut is on stable and reliable industrial applications where the quality of the solvent or feedstock directly affects the quality of the final product.

Technical Specifications

• Aromatic content: minimum 99%
• Non-aromatic content: maximum 1%
• Density at 15.56°C: minimum 0.91 g/cm³
• Flash point: minimum 70°C
• Total sulfur: maximum 1 ppm (wt)
• IBP (Initial Boiling Point): minimum 190°C
• FBP (Final Boiling Point): maximum 370°C

These specifications make the product safe, stable, and consistent for industrial use.

Main Applications

1. Industrial solvent for paints, resins, and coatings

Thanks to strong solvency power, this aromatic fraction is widely used in:

• Industrial and architectural paints
• Alkyd and industrial resins
• Varnishes and protective metal coatings

Its use improves product uniformity, formulation stability, and final surface quality.

2. Feedstock for hydrocarbon (C9) resin production

Feedstock quality is critical in resin manufacturing due to:

• Stable chemical composition
• Controlled boiling range
• High content of true aromatics

It enables better control over final resin properties in C9 and modified resin production.

3. Rubber and tire industry

Used as a component in process oils and plasticizers, offering:

• High compatibility with rubber structures
• Improved flexibility and durability
• Enhanced extrusion and molding performance

This leads to improved product performance and reduced production waste.

4. Use in fuels and industrial blenders

Due to suitable density and high aromatic content, it is used in selected industrial fuel and blending formulations. Extremely low sulfur content makes it suitable for applications with strict quality standards.

5. Downstream chemical industries

Used as a solvent or feedstock in:

• Adhesives and industrial additives
• Specialty chemicals
• Construction and industrial compounds

Its stability ensures consistent quality in large-scale production.

Competitive Advantages

• Reduced risk of final product quality fluctuations
• Improved production process stability
• Lower equipment wear and tear
• Better compatibility with sensitive formulations

Conclusion

Heavy Aromatic is a key material for downstream industries, offering wide applications, stable performance, and real value creation. Selecting a product with precise technical specifications directly impacts quality, productivity, and overall production costs.

For manufacturers seeking a reliable industrial solvent or feedstock, this material represents a technically and economically sound choice.
