PEO-Polyethylene Oxide

PEO-Polyethylene Oxide

What is Polyethylene Oxide 

 

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.

General Properties


1. Water-soluble thermoplastic resin,so PEO can be used for extrusion molding, foundry molding, and calendaring molding.

2. Also soluble in various organic solvents, can forms associated molecules with chemical compounds with high polarity such as urea, acrylic resin, and phenoi resin.

3. Non-ionic.

4. When dissolved, the solution show high viscosity even at low density, making PEO an effective thickener.

5. Products with high-molecular weights are viscoelastic,so their aqueous solutions can reduce spattering and misting, and have dispersing and coagulation properties.

6. Cant be broken down by bacteria.Films of PEO are flexible, tough and resistant to most oils and greases.

7. Aqueous solution reduces friction resistance.


Function including as follows,


1. Film Former-

Resistant to oil and greases; Compatible with other resins and plasticizing agents.

2. Wet Tack- Sticky wet adhesives; Non-tacky when dry.

3. High Binding Efficiency--Outstanding binder for inks, pigments, ceramics, metal powders, fillers and more; Burns off clean at low temperatures

4. Cross-linkable-- Can form highly water-retentive gels by irradiation without initiators or co-agents.

5. Flocculant--Adheres onto colloidal materials;Efficiently separates fines from aqueous systems.

6. Viscoelasticity--Reduces splattering; Controls drift and misting when sprayed;Pituitous.

7. Lubricity-Super ability the lubricity,reduce the most friction.

8. Thermoplasticity--Readily extruded, calendared, injection-molded or cast; Heat-sealable and orientable.

9. Froms Novel Complexes--Associates with polar compounds such as phenolic resins, mineral acid, urea,etc.

10. Sulubility in Organic Solvents--Thickens ketons, alcohos, esters and some hydrocarbons; Not generally soluble in glycols, diols and aliphatic ethers.

11. Low Toxicity--Pooly absorbed and non-irritant

12. Drag Reduction-- Concerves energy by reducing turbulent friction for fluids

13. Thickening--Large range of viscosities that can be customized; Compatile from pH 2 to 13; Non-ionic and pseudoplastic.

Dissolving

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

  

Packaging and Storage                                                               

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.
