Description

Hydrocarbon Oils, Arom. CAS NO 78308-32-4 refers to a specialized class of aromatic hydrocarbon oils, characterized by their complex mixture of alkylated aromatic compounds. These oils are valued for their excellent solvency power, thermal stability, and compatibility with a wide range of polymers and resins. They are essential raw materials and process aids in industries such as polymer manufacturing, rubber processing, and specialty chemical formulation.

Application

• As a plasticizer and processing aid in the production of rubber and synthetic polymers.
• As a solvent and carrier fluid in the formulation of adhesives, sealants, and coatings.
• As a extender oil in tire and rubber goods manufacturing to modify compound properties and reduce costs.
• As a chemical intermediate in the synthesis of surfactants and other specialty chemicals.
• As a heat transfer fluid component in specific industrial systems.
• In the production of carbon black feedstock and other petroleum-derived products.

Quality Control

Our Hydrocarbon Oils, Arom. are produced and tested under a stringent quality management system to ensure batch-to-batch consistency and performance. Key parameters such as viscosity, aniline point, flash point, and aromatic content are rigorously controlled. A Certificate of Analysis (COA) detailing specific test results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep containers tightly sealed when not in use to prevent contamination and minimize evaporation.
