聚环氧乙烷（PEO），也称为聚环氧乙烷，是结晶的热塑性水溶性聚合物。相对分子质量为1x105至1x106的产物称为聚环氧乙烷。PEO聚氧乙烯是一种白色流动性粉末，分子结构为（CH2CH2O）。这种树脂的反应性端基的浓度低，并且没有明显的端基活性。
产品应用
它完全溶于水，可溶于某些有机溶剂。它的溶液在低浓度时具有很高的粘度。
它是具有柔韧性和高强度的热塑性树脂。可通过压延，挤压，铸造等加工；
耐细菌侵袭，无腐蚀性，在大气中一般不吸湿；
聚合物中的聚合物具有絮凝作用；
与其他树脂的相容性好。PEO具有延展性，并且当温度高于树脂的熔点时，高分子量PEO变成热塑性的。有时需要向树脂中添加增塑剂或其他热塑性树脂，这一方面便于加工，另一方面又具有良好的PEO复合性能。尽管PEO易溶于水，但由于其高结晶度，与其他水溶性树脂相比，其吸热性能非常低。PEO和某些树脂具有良好的相容性，这为PEO的改性提供了有利的条件。
PEO Polyethylene Oxide for Water-based thickener
Polyethylene oxide hot melt resin PEO
PEO Custom processing of polyethylene oxide of various molecular weights
Chemical Name : Polyethylene oxide PEO;
Molecular formula : H-(-OCH2CH2-)n-OH;

Polyethylene oxide (PEO), also known as polyethylene oxide, is a crystalline, thermoplastic water-soluble polymer. The product with a relative molecular mass of 1x105 to 1x106 is called polyethylene oxide. PEO polyoxyethylene is a white flowable powder with a molecular structure of (CH2CH2O). The concentration of reactive end groups of such resins is low and there is no obvious end group activity.
Product Application
It is completely soluble in water and soluble in some organic solvents. Its solution has a very high viscosity at low concentrations;
It is a thermoplastic resin with flexibility and high strength. Can be processed by calendering, extrusion, casting, etc.;
Resistant to bacterial attack, not corrosive, and generally not hygroscopic in the atmosphere;
The polymer of the polymer has a flocculation effect;
Good compatibility with other resins. PEO has extensibility, and when the temperature is higher than the melting point of the resin, the high molecular weight PEO becomes a thermoplastic. It is sometimes necessary to add a plasticizer or other thermoplastic resin to the resin, which is convenient for processing on the one hand and good composite properties of PEO on the other hand. Although PEO is easily soluble in water, its heat absorbing property is very low compared with other water-soluble resins due to its high crystallinity. PEO and some resins have good compatibility, which provides favorable conditions for the modification of PEO.
