Chemical Profile

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 product is manufactured for industrial and commercial applications where high purity is required for consistent performance.

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.
