Polyglycol Methylether

Edition Date :
October 19, 2022
Polyglykol MA 750 is a linear, mono hydroxy-functional polyethylene glycol monomethyl ether (M-PEG) that is completely water soluble. Polyglykol MA 750 is esterified with methacrylic acid to yield the corresponding polyglycol mono methacrylates which are used for the polymerization of polycarboxylate superplasticizers.

Packaging and Storage

Delivery form
Liquid

Packaging
Stainless steel or aluminium containers with external heating coil.

Storage
Polyglycols in sealed original packaging have a shelf life of 2 years if stored in a cool, dry place.

Exclusion of moisture is very important, since liquid PEGs are hygroscopic and the solid types absorb any moisture they are exposed to due to their good solubility in water. Each time the containers are opened, they should be resealed to make them airtight.

The storage temperature should not exceed 90°C. The storage tank must have a circulation loop, top to bottom, with a dry nitrogen blanket to prevent product oxidation/degration.
