High quality Polyethylene glycol monomethallyl ether HPEG(or VPEG) cas 31497-33-3
Product details:
Product Name: Polyethylene glycol monomethallyl ether HPEG
CAS: 31497-33-3
MF: CH2=C(CH3)CH2O(CH2CH2O)nH
Applications :
HPEG is non-toxic, non-irritant with good water solubility and will not be hydrolytic deteriorated.
It has good intermiscibility with many compounds. It is an important raw material for polycarboxylate water reducing agent which has good dispersibility holding facility.
It has the advantage of low mixing quantity, high water reducing rate, good strength enhancing effect, durability, low steel corrosion and environment protection.
It can be used in the commercial concrete which is available to on-site stirring and long-distance transportation with high performance and intensity (over C60) .
Packing:
25kg/bag or 1000kg/bag
Storage should be at cool, dry and ventilate.
