TPEG 909 (TPEG-2400)

———

TPEG is the abbreviation for Isopentenyl Polyoxyethylene Ether. It is a non-ionic, polyether-based macromonomer that serves as one of the most important and widely used raw materials for synthesizing Polycarboxylate Superplasticizers (PCEs).
Chemically, TPEG is produced by reacting isoprenol (a five-carbon unsaturated alcohol) with ethylene oxide (EO) in the presence of an alkaline catalyst. This process results in a molecule with a unique structure.

Product details

Description

Isopentenyl alcohol polyethoxylated ether 2400 (TPEG 909) with a molecular weight of 2400, is a macromonomer for PCE, produced primarily from isopentenyl alcohol and ethylene oxide.

Chemical formula

CH2=C(CH3)-CH2O-CH2O- (CH2CH2O)n-Hn≈53

Product Applications

Isopentenyl polyoxyethylene ether TPEG 909 is produced using a world-leading fully automated production line and a novel polymerization catalyst system, featuring a narrow molecular weight distribution, consistent quality, low impurity content, and high polymerization reactivity.The water-reducing admixture produced by the company offers outstanding slump retention, excellent adaptability, and superior overall performance. It delivers significant slump retention benefits in concrete applications and is suitable for long-distance transport.
