Purity / Grade Guide

Technical grade is the industrial tier: supplied for coatings, adhesives, cleaning, degreasing and general process work where certified trace-impurity limits are not written into the protocol. A lot-specific Certificate of Analysis is available on request. If your SOP names a higher analytical tier, specify that grade when you order — this product is not supplied to those specifications.

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 Technical 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 technical or technical-contact purity standards.
