My solid polymer electrolyte for lithium battery needs high mechanical strength. Can PEG20000 be used?
Yes, but it is crystalline at room temperature; blend with low MW PEG or plasticizers.

Is PEG20000 suitable as a lubricant for high-speed metal forming?
Yes, applied as a hot melt or aqueous dispersion; provides excellent film strength.

My textile finishing needs a permanent anti-static effect. Can PEG20000 provide it?
Its high MW reduces migration, giving longer lasting effect.

What is the melting point of PEG20000?
Approximately 66–68°C; higher than lower MW PEGs.

My ceramic slip casting needs a binder that burns out very slowly. Is PEG20000 suitable?
Yes, its slow decomposition allows controlled burnout without cracking.

Does PEG20000 absorb moisture as much as lower MW PEGs?
Less hygroscopic due to lower mass ratio of end groups; still requires dry storage.

My medical adhesive needs a water-soluble backing. Can PEG20000 be used?
Yes, it can be cast into films for temporary skin adhesives.
