Polyethylene Glycol

Polyethylene Glycol (PEG) is a water-soluble polymer produced by the polymerization of ethylene oxide, with a molecular weight range of 200 to 8000. It features excellent lubricity, moisture retention and chemical stability, and is a core raw material in the fields of medicine, cosmetics and industry. The product is a colorless and transparent liquid (MW<600)/waxy solid (MW>1000). Its water solubility, low toxicity and biocompatibility are excellent, and it is widely used in medicine (slow release preparation), daily chemical (moisturizing agent), industry (metal processing fluid) and other fields.
