Product properties of Polyglykol PR 450:
Polyglykol PR 450 is a clear neutral liquid at room temperature.
Polyglykol PR 450 can be supplied in tank trucks or in steel drums.
Its two hydroxy end groups as well as its ether groups mainly control the physical and chemical properties of Polyglykol PR 450.
Therefore Polyglykol PR 450 is soluble in water and polar organic solvents like aceton or methanol.
Polyglykol PR 450 is insoluble in pure hydrocarbons.
Polyglykol PR 450 displays typical chemical reactions of alcohols/diols.
The solidification point, of Polyglykol PR 450 is about 30 °C lower than that of the polyethylene glycol 400.
This simplifies handling of Polyglykol PR 450 at low temperatures.
Besides the lower solidification point properties in general are very similar to polyethylene glycol 400.
Storage of Polyglykol PR 450:
When stored in a cold, dry place in a closed container Polyglykol PR 450 can be kept for at least two years.
Applications of Polyglykol PR 450:
Based on their physical and chemical characteristics PR-type polyglycols similar to polyethylene glycols are used for a wide variety of applications.
Fields of industrial applications of Polyglykol PR 450:
- Reactive diol/polyether component in polyester or polyurethene resins
- Component of auxiliaries for leather and textile processing
