Introduction
Industrial - grade propylene glycol is a colorless, transparent, viscous liquid with a mild odor. It has excellent solubility in water and many organic solvents. It is mainly used in the industrial field as a solvent, antifreeze, heat - transfer medium, and raw material for the synthesis of various chemicals. It is an important intermediate in the production of polyester resins, polyurethanes, and other polymers.
Advantages
• Good Solvent Properties: It can dissolve a wide variety of organic and inorganic substances, making it an excellent solvent in many chemical processes.
• Low Toxicity: Compared to some other glycols, industrial - grade propylene glycol has relatively low toxicity, which is beneficial for handling and using in industrial applications.
• High Boiling Point and Low Freezing Point: It has a high boiling point, which ensures its stability at high temperatures, and a low freezing point, allowing it to be used in low - temperature environments without easily freezing.
• Excellent Heat - Transfer Properties: It has good heat - transfer performance, which can effectively transfer heat in heat - transfer systems, improving energy - utilization efficiency.
• Chemical Stability: It has good chemical stability and is not easily affected by chemical reactions in most environments, ensuring its quality and performance during storage and use.
