HPEG-2400 (Hydroxy Polyethylene Glycol-2400)
HPEG-2400, chemically known as Isopentenyl Polyethylene Glycol, is a non-ionic surfactant and a vital macromonomer for the construction chemical industry. Produced through the ethoxylation of 3-methyl-3-buten-1-ol (Isopentenyl alcohol), it features a reactive double bond at one end and a hydroxyl group at the other. This unique structure allows it to undergo free-radical copolymerization with acrylic acid to form Polycarboxylate Superplasticizers (PCE). Moonarc Chemicals provides HPEG-2400 that is optimized for high reactivity, low impurity content, and excellent structural stability, ensuring high-performance water reduction in concrete applications.
