Composition of Polyglykol M 250:
Monomethoxy polyethylene glycol
CAS Number: 9004-74-4
Polyglykol M 250 is a monomethoxy polyethylene glycol with a molecular weight of 283 – 295g/mol.
Polyglykol M 250 can be considered as high molecular alcohol and therefore displays typical chemical reactions of alcohols.
M-type polyglycols are used for a wide variety of chemical reactions.
With isocyanates and polyester they act as endcapping and hydrophilic component.
When reacted with unsaturated monomers like acrylic or methacrylic acid esters are formed which can be copolymerisized in order to increase hydrophilicity and improve dispersing properties of polymers in water.
Product properties of Polyglykol M 250:
Polyglykol M 250 is a clear neutral liquid at room temperature.
Polyglykol M 250 can be supplied in tank trucks or in steel drums.
Polyglykol M 250 is soluble in water and common used organic solvents like Aceton, Methanol.
Polyglykol M 250 can be considered as high molecular alcohol and therefore displays typical chemical reactions of alcohols.
Storage of Polyglykol M 250:
When stored in a cold, dry place in a closed container Polyglykol M 250 can be kept for at least two years.
Applications of Polyglykol M 250:
M-type polyglycols are used for a wide variety of chemical reactions.
