Description

Used Oil Vacuum Distillation Bottoms is a complex hydrocarbon residue derived from the vacuum distillation of used lubricating oils, with the CAS registry number 129893-17-0. This material is a critical intermediate and feedstock for various industrial processes, valued for its high carbon content and specific rheological properties. It is primarily utilized by manufacturers in the asphalt, fuel blending, and specialty carbon industries seeking cost-effective and sustainable raw materials.

Application

• As a fluxing agent and softener in the production of industrial-grade asphalt and roofing materials.
• As a heavy fuel oil component and blending stock for marine fuels or industrial burners.
• As a feedstock for further processing into re-refined base oils or lubricant additives.
• As a carbon source and binder in the manufacture of carbon black, graphite, or other carbon-based products.
• For use in industrial sealants and waterproofing compounds.
• As a dust suppressant and road oil for unpaved surfaces.

Quality Control

Our Used Oil Vacuum Distillation Bottoms is produced and controlled under a stringent quality management system. Each batch is characterized for key parameters to ensure consistency and suitability for its intended industrial applications. Certificates of Analysis (COA) detailing viscosity, flash point, ash content, and carbon residue are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Keep container tightly sealed when not in use to prevent contamination and minimize evaporation of lighter fractions. Compatible storage materials should be selected based on its strong acid/organic solvent nature.
