AROMATIC HAVIES

About AROMATIC HAVIES

Aromatic heavies are a group of high-boiling aromatic hydrocarbon solvents primarily composed of C9C12 alkyl benzenes and polyaromatic compounds. They are derived from petroleum refining processes such as catalytic reforming and steam cracking.

These solvents are characterized by:

• High solvency power
• Slow evaporation rate
• Strong compatibility with resins and polymers

They are widely used in coatings, inks, agrochemicals, rubber processing, and industrial cleaning formulations due to their ability to dissolve heavy, non-polar substances efficiently.
