MPEG-3000

MPEG(methoxy polyethylene glycol) is made by reaction with EO (etheylene oxide) and Methanol and MPEG's main usage is producing PCA type (polycarboxylate) water reducing agent.

MPEG normally reacts with MAA (metha acrylic acid) through esterification and generate Macromer (MPEG-MA) and Macromer further reacts with MAA (metha acyrlic acid ) and other polymer. And its final products called PCA (polye carboxylate type water reducing agent) which are currently applied in high speed railways, multistory building, subways and so on which normally required high strength and excellent durability.
