It can be completely dissolved in water and some organic solvent The solution has high stickiness in low temperature£»
It is a flexible, high strength thermoplastic resin .It can be processed with rolling, extrusion and casting£»
It can resist the erosion of bacteria and cannot be decayed. The character of absorbing humidity is not obvious in the air£»
Macromolecule polymer has a function of flocculation£»
It is easy to unite with other resin.

Uses and security

PEO can be safely used in many special aspects. Union Carbide Corporation in The U.S. makes a research with dogs, mice and rabbits. American Navy Seabed Centre made a research with many marine lives. These researches show that the toxic of HMW PEO is very low in oral application. Because of its big molecular weight, it¡¯s difficult to be absorbed by intestinal canal.

Packing of products
