Description

HPEG 2400 Polycarboxylate Polyether Monomer is the basic raw material of high-performance water-reducing agent-polycarboxylate-based high-efficiency water-reducing agent, using the most advanced ethoxylation technology and production equipment. The final product has accurate molecular weight, low glycol content and white appearance. When preparing the reducing agent, sudden polymerization and viscosity increase will not occur.

Technical Formula

CH2=C(CH3)CH2O (CH2CH2O)nH, n=10~60. HPEG 2400 is a polyoxyethylene monomethallyl ether with molecular weight 2400.

Principle

HPEG 2400 Polycarboxylate Polyether Monomer is the main raw material for high performance polycarboxylate superplasticizer with the properties of non-toxic, non-corrossive and good water-soluble. High performance polycarboxylate superplasticizer made from HPEG 2400 has such advantages as superior dispersing maintenance, low dosage, high water reducing ratio, good adhensive property, good reinforcing effects, good durability, no corrosion to steel bar and environment-friendly etc. PCE made from HPEG 2400 can be used to produce high performance, high strength commercial concrete at work site or long-distant convey.
