Quality Control

Our Pentaerythritol Propoxylate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for hydroxyl value, viscosity, water content, and color. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
