详细说明
聚醚多元醇/9003-11-6 P123 (分子量:5800) 型号:BS32-435465(L)
库号:M147909  

Poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol)
average Mn ~5,800
CAS Number:9003-11-6
Descriptions
Packaging: 1 L in poly btl
250 mL in poly btl
Physical form : Terminal primary dihydroxy-functional oligomer.
Application: Hard and soft surface cleaners, defoamers in coatings and water treatment. Lubricant in metal working, anti-foaming aid and extender for linear and cross-linked polyesters and polyurethanes.
Features and Benefits: Surface active material whose properties are dependent on the hydrophilic (EO)/hydrophobic (PO) ratio. High EO content gives better o/w stabilizers.
