Tripropylene Glycol (Acrylate Grade) (TPG Ac) is a high purity tripropylene glycol containing only low levels of carbonyls and peroxides, which makes it ideal for use as a reactive chemical intermediate in the irradiation curing industry.
Tripropylene Glycol is a co-product of the reaction of excess water with propylene oxide at elevated temperatures and pressures to make propylene glycol, a colorless, water-soluble, low-toxicity, low-vapor pressure, moderately viscous, hygroscopic liquid with a slight odor characteristic of diols.

·The acidity, aldehyde content, and peroxide content in tripropylene glycol (acrylate grade) are strictly and specifically monitored to avoid product color change or operational problems during the synthesis of the diacrylate. These impurities are controlled in the low ppm range.
·Tripropylene Glycol (Acrylate Grade) is used in industrial applications only.
