HPEG, one type of polyether monomer or polycarboxylate ether monomer, is polymerized by methallyl alcohol and ethylene oxide and is the main material for the synthesis of Polycarboxylate Superplasticizer (PCE).
Chemical Structure: CH2=C(CH3)-CH2-O-(CH2CH2O)n-H (HPEG-2400/3000 according to the “n” of “CH2CH2O” )
Product Categories: Polyether Monomer / Polycarboxylate Ether Monomer
HPEG, one type of polyether monomer or polycarboxylate ether monomer, is polymerized by methallyl alcohol and ethylene oxide. Firstly, these important materials of the polycarboxylic water-reduce agent/polycarboxylate superplasticizer (PCE), which is the most used concrete admixture(cement additive) in modern concrete, have a great effect on dispersing cement pellets. Secondly, these product is soluble in water with Non-toxic for the synthesis of PCE. Thirdly, these environmental-friendly products feature a small dosage and good effect on reducing water and strengthening. Furthermore, the final water-reduce agent shows great durability and is rustproof against seel bar.
This series of products adopt international advanced alkoxylation devices, catalytic processes, and production technology. Therefore, the final products feature accurate molecular weight, low glycol, high content, high double-bonding, and high retention rate. Finally, the prepared water-reduce agents feature good cohesion and slump.
