Description

HPEG is a kind of main raw material (polycarboxylate ether monomer) for producing high performance water reducing type polycarboxylate superplasticizer , it is produced with methallyl alcohol and ethylene epoxide as main raw materials.


Chemical formula

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


Principle

This product 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.
