PEG Polyethylene glycol CAS 25322-68-3

About PEG Polyethylene glycol : PEG Polyethylene glycol with lower relative molecular weight (PEG200~600) has solubilization, solubilization, moisture retention, heat carrier performance. Relatively high molecular weight is commonly used as matrix, play a role in regulating viscosity, melting point, stability system.
is a trusted global Polyglyceryl-10 Oleate. Feel free to send an inquiry to get the latest pr ce of PEG Polyethylene glycol if you would like to buy PEG Polyethylene glycol in bulk.

Product Performance of PEG Polyethylene glycol:
The end group of polyethylene glycol is hydroxyl, which can be esterified and other reactions. Polyoxyethyl is easy to associate with electron receptors such as polyacrylic acid, urea or tannic acid, and automatic oxidation will occur, so anti-aging agent must be added. It is soluble in water, but its solubility decreases as it approaches the boiling point of water. In addition, it is soluble in acetonitrile, carbon tetrachloride, dichloroethane and thermal benzene and other organic solvents. The molecular weight distribution of high molecular weight polymers is very wide :Mw/Mn=15~20(Mw heavy average molecular weight,Mn number average molecular weight). Regular structure, spherulite, crystallinity up to 95%. Melting point 62~66, can be extrusion molding. Tensile strength is close to medium density polyethylene. When relative humidity is below 70%, water absorption is only below 5%, which has almost no effect on strength.
Polyoxyethyl is soluble in water and helps reduce friction from turbulence, reducing pipe resistance by 50% with only 6ppm.
