Propylene Glycol - Doug's Tip of the Month
Propylene Glycol (PG) is a versatile, non-toxic heat transfer fluid widely used across numerous industries due to its ability to lower the freeze point of water and operate efficiently within a broad temperature range of -50°F to 325°F. From critical applications like HVAC systems, solar heating, and thermal energy storage to specialized uses in food processing, cosmetics, and industrial manufacturing, PG-based antifreezes and coolants offer reliable performance and safety. When formulated with virgin glycols and high-quality additive packages, PG antifreezes provide excellent corrosion resistance, pH stability, and extended fluid life—making them essential for optimizing equipment longevity and performance across a wide range of demanding environments.
Propylene Glycols have many uses including but not limited to:
