Quality Control

Our Chlorinated Paraffin is manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through parameters including chlorine content, viscosity, color, and acid value. A Certificate of Analysis (COA) documenting these specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to prevent moisture absorption and maintain product integrity.
