Chemical Name: PEG 1000
Function: Intermediate
CAS Number: 25322-68-3
Chemical Family: Polyethylene Glycols, Polyols
Polyethylene glycol monomethyl ether.
Polyglykol M 1000 is a linear, mono hydroxy-functional polyethylene glycol monomethyl ether (M-PEG) that is completely water soluble.
Polyglykol M 1000 is a linear, mono hydroxy-functional polyethylene glycol monomethyl ether (M-PEG).
Polyglykol M 1000 has low diol content to limit the formation of crosslinking diesters.
When Polyglykol M 1000 reacted with unsaturated monomers like acrylic or methacrylic acid, esters are formed which can be copolymerized in order to increase hydrophilicity and improves dispersing properties of polymers in water.
Moreover, Polyglykol M 1000 is esterified with methacrylic acid to yield the corresponding polyglycol mono methacrylates, which are used for the polymerization of polycarboxylate super-plasticizers.
Benefits of Polyglykol M 1000:
-Polyglykol M 1000 has a low diol content to limit formation of crosslinking diesters
-Polyglykol M 1000 is completely water soluble
Product Function:
-Intermediate
Applications of Polyglykol M 1000:
-Lubes and Greases
-Industrial Lubrication
-Paint additive manufacturing
-Construction
-Grinding Aids
-Concrete Admixture
-Dry mix mortars
-Plaster Boards
-Superplasticizer
Recommended Uses of Polyglykol M 1000:
M-type polyglycols are used for a wide variety of chemical reactions.
With isocyanates and polyester they act as endcap and hydrophilic component.
When reacted with unsaturated monomers like acrylic or methacrylic acid esters are formed which can be copolymerized in order to increase hydrophilicity and improve dispersing properties of polymers in water.
Due to the low concentration of diols in Polyglykol M- types there is almost no formation of di-esters during the reaction with unsaturated organic acids.
