PEO-Polyethylene Oxide Powder
Material Safety Data Sheet(MSDS)-Polyethylene Oxide Powder-Shandong Charing.pdf
Polyethylene Oxide(PEO) is a nonionic water-soluble thermoplastic resin with properities that include excellent coagulation,binding effect, thickening, and friction reduction.
Polyethylene Oxide(PEO) is obtained through the heterogeneous polymerzation of ethylene oxide(CH2CH2O)N, which in turn creates poly(ethylene oxide) or PEO.
Polyethylene Oxide(PEO) is a high-polymer polyethylene oxide with high molecular weights ranging from 150,000 to 10 million, which is created from the polymerzation of ethylene oxide.
Polyethylene Oxide(PEO) can be used in a wide range of applications, can meet specific formulation and processing requirements.

Methods for Dissolving PEO in Aqueous Solution
PEO dissolves completely in water, but in order to achieve total dissolving, the PEO must first be completely dispersed.
It takes about 05-4hours to dispersing into water. To dispersing the powder with minimal shear is important to facilitate complete dissolution. If the resins are added too quickly, the will form ge;-coated agglomerates that prevent complete hydration.
There are three major techniques that ensure sufficient dispersion of PEO resin particles, but the choice depends on the final viscosity target and required volume.
1. Direct addition to water
PEO is suggested to be slowly added to water while the water is being stirred. It will takes long time.
2. Pre-dispersion in water-miscible non-solvents
Another method that can be used is to first make a slurry of PEO in water-soluble solvent medium, and then add water.
PEO is first dispersed in a water-miscible non-solvent, such as isopropyl alcohol, to separate the individual partivles from each other. Each individual particle has a chance to swell, hydrate and dissolve. This techniques avoids the typical clumping that occurs when dissolved in water alone. The use of alcohols or glycols has the added benefit of stabilizing the solution viscosity over time
A. Standard Packing:In 20kg/barrel.
B. Standard Packing:in 15kgs carton inner PE bags.
C. Standard Packing: In 20kg/ bags inner PE bags
Big Bag or other special packages are possible on request.
Store it in a cool, dark place away from direct sunligh, rain, dew , high humidity and heat resources. The temperature in the storage area should not exceed 30℃.
If PEO powder spills onto the floor and gets wet, it will become very slippery, so need to pay attention when working around split PEO.
