Heavy Aromatic Extract (HAE)

Description

1. Product Overview
Heavy Aromatic Extract is a refined aromatic-rich hydrocarbon fraction derived from vacuum distillation of crude oil streams, specifically engineered as a processing oil and extender for elastomers and plastics. Its primary industrial use is in tire manufacturing (SBR/BR rubber extension), PVC plastisol viscosity reduction, and waterproofing membrane production. The key value proposition is superior aromaticity (high CA value) enabling better carbon black dispersion and lower volatility than paraffinic or naphthenic oils. Strategically, HAE mitigates raw material substitution risks and reduces compound viscosity without compromising tensile strength—critical for high-throughput industrial compounding.

2. Key Specifications & Technical Characteristics

• Chemical composition: Complex mixture of polycyclic aromatic hydrocarbons (PCA content < 3% by IP346 for non-carcinogenic grades; standard grades up to 10–15%)

• Purity/grade: High-aromatic grade (CA% ≥ 40); viscosity grade: 50–120 cSt @ 40°C

• Physical characteristics: Dark brown to black viscous liquid; density 0.98–1.10 g/cm³ @ 15°C; flash point > 200°C; pour point -15°C to +5°C

• Packaging options: Bulk ISO tank, flexitank (20 MT), steel drums (200 kg net)

• Shelf life: 24 months in sealed, moisture-free conditions; no polymerization risk

3. Core Industrial Applications

• Primary industries: Tire & rubber manufacturing, PVC compounding, industrial adhesives, roofing membranes, asphalt modification

• Operational use cases: As an extender oil in SBR/BR tire tread compounds; as a viscosity depressant in plastisols for automotive underbody coatings; as a softening agent in EPDM profiles

• Performance advantage: Higher aromatic content (CA > 40%) improves filler wetting and dispersion kinetics by 30–40% versus paraffinic oils, reducing mixing energy. Better compatibility with polar polymers yields higher modulus retention under heat aging. Cost advantage: replaces more expensive synthetic plasticizers (e.g., DOTP, DOP) in non-phthalate-sensitive applications.
