EPEG 912 (EPEG 3000)

EPEG 912 (EPEG 3000)

———

EPEG is the abbreviation for Ethylene glycol monovinyl polyethylene glycol ether (also referred to as a VPEG-type macromonomer in some literature). It is a novel, high-performance macromonomer specifically designed for synthesizing Polycarboxylate Superplasticizers (PCEs) .

Chemically, EPEG belongs to the vinyl ether family of macromonomers. This means its reactive terminal double bond is directly linked to an oxygen atom (C-O-C structure), which significantly alters its electron density and gives it a distinct advantage over other macromonomers—exceptionally high polymerization reactivity.

Product details

EPEG 3000 (EPEG-912)

Description

Ethylene glycol monomethyl polyethoxylated ether 3000 (EPEG 912) with a molecular weight of 3000, is a macromonomer for PCE, produced primarily from ethylene glycol monovinyl ether and ethylene oxide.

Chemical formula

CH2=CH-O-CH2-CH2-O-(CH2CH2O)n-Hn≈66


Product Applications

EPEG 912 is a new type of ether-based PCE macromolecule used in the production of PCE. It offers excellent performance, with high double-bond polymerization activity, enabling polymerization at low temperatures or room temperature, significantly reducing response time, saving energy, and lowering costs. The water-reducing agent produced by the company exhibits strong cement particle dispersion and retention properties, performs well with clay-rich aggregates, and delivers good concrete workability and performance.
