Quality Control

Our Distillates, Petroleum, Steam-Cracked, Medium, Polymerised is produced under a rigorous quality management system. Each batch undergoes comprehensive analysis to ensure consistency and meets agreed-upon specifications for parameters such as viscosity, bromine number, and distillation range. Certificates of Analysis (COA) documenting these results 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 incompatible materials such as strong acids, organic solvents, and strong oxidizing agents. As this material is easily oxidized, storage under an inert atmosphere (e.g., nitrogen blanket) is recommended for long-term preservation of quality. Keep container tightly sealed when not in use to prevent evaporation and contamination.
