Different molecular weight structures of polyethylene glycol and its application fields With the continuous expansion of the application field of polyethylene glycol, the production of polyethylene glycol in countries and regions such as Europe, America and Japan has increased rapidly. There are various types of polyethylene glycol products in foreign countries. The structure of poly(ethylene glycol) is HOCH2[CH2OCH2] nCH2OH or H[ OCH2CH2] nOH is a general term for ethylene glycol polymers having an average molecular weight of 200 to 8000 or more. With the difference in average molecular weight, the properties also vary.

Various types and uses of polyethylene glycol Its main products are PEG-200,PEG-400 ,PEG-600 ,PEG-800,PEG-1000, PEG-1500,PEG-4000 and PEG-6000 .

Application of polyethylene glycol series products in biomedical field The polyethylene glycol series products are non-toxic, non-irritating, slightly bitter, have good water solubility, and have good compatibility with many organic components. They have excellent lubricity, moisture retention, dispersibility, adhesives, antistatic agents and softeners in cosmetics, pharmaceuticals, chemical fiber, rubber, plastics, paper, paint, electroplating, pesticides, metal processing and food processing.
