What are the characteristics of Polyethylene oxide/PEO?

Polyethylene oxide (PEO), also known as polyethylene oxide, is a kind of crystalline, thermoplastic water soluble polymer.  Query the chemical dictionary can see polyvinyl oxide has a lot of English translation of the name, which is used in Germany PEO abbreviation is the most common, PEO polyvinyl oxide product molecular weight can be in a wide range of changes.  The German Sakuras Group only produces high viscosity, relative molecular mass 200 ~ 20000 products called polyethylene glycol (PEG), they are viscous liquid or waxy solid:  The product with molecular relative mass of 1x105 ~ 1x106 is called polyvinyl oxide. PEO polyvinyl oxide is a white flowing powder with molecular structure of (CH2CH2O). The concentration of active end groups of this kind of resin is low, and there is no obvious end group activity.

Features :

Completely soluble in water, soluble in some organic solvents.  Its solution has high viscosity at low concentration;  

It is a soft, high strength thermal plasticity resin.  It can be processed by rolling, extrusion and casting.  

Resistant to bacterial erosion, not spoilage, moisture absorption in the atmosphere is usually not large;  

The polymer of high polymer has flocculation effect;  

Good compatibility with other resins.
