Product Overview

Propylene Glycol 20% Technical Grade is a pre-diluted aqueous solution formulated for industrial applications that need a low-toxicity heat transfer fluid, freeze-point depressant, or process carrier without the cost profile of higher-purity USP feedstock. The 20% concentration is ready to use and helps maintain consistent performance without on-site mixing.

This technical-grade blend is typically selected for closed-loop cooling, light-duty freeze protection, and general manufacturing applications where consistent concentration and straightforward handling are more important than pharmaceutical or food-contact purity standards.

Key Properties

  • Concentration: 20% Propylene Glycol / 80% Water
  • Grade: Technical Grade
  • Appearance: Clear, colorless liquid
  • Formula: C3H8O2
  • CAS Number: 57-55-6
  • Specific Gravity (20°C): 1.012
  • Solubility: Fully miscible with water
  • Use Profile: Industrial cooling, freeze moderation, and general process use

Common Applications

  • HVAC & Chillers: Used as a low-concentration glycol fluid in light-duty building and equipment cooling loops.
  • Industrial Antifreeze: Helps reduce freeze risk in moderate climates and seasonal shutdown conditions.
  • General Manufacturing: Suitable for process systems that require a consistent glycol-water blend for circulation or flushing.
  • Utility Systems: Used in maintenance programs for auxiliary equipment, jackets, and non-critical piping loops.

Safety Precautions

Store in a cool, dry, well-ventilated area and keep containers tightly closed when not in use. Wear appropriate PPE, including gloves and eye protection, during handling. Review the SDS before use for detailed handling, spill-response, and disposal requirements.
