Polyethylene glycol 3350 – uses

Poly (ethylene oxide) resin is a high molecular weight homopolymer formed by ring opening polymerization of ethylene oxide by heterogeneous catalysis. The former is called polyethylene glycol and the latter is polyoxyethylene. Polyethylene oxide (PEO) has the properties of flocculation, thickening, slow release, lubrication, dispersion, retention and water retention. It is suitable for medicine, chemical fertilizer, papermaking, ceramics, detergents, cosmetics, heat treatment, water treatment, fire protection, oil exploitation and other industries. The product is non-toxic and non irritant, and will not remain, deposit or breed volatile substances in the product generation process. As a papermaking additive, it can increase the retention rate of filler and fine fiber, especially suitable for dispersant of long fiber and shorten beating time. It can be used as mold agent for metal processing, lubricant and cutting fluid for metal drawing, stamping or forming, grinding and cooling lubrication, polishing agent, welding flux, etc. in the paper industry, it is also used as a lubricant and hot-melt adhesive to increase the rapid rewetting ability.
Polyethylene glycol 3350 – Safety

It has little irritation to skin and eyes, and is difficult to be absorbed by gastrointestinal tract after oral administration, and the toxicity is very low. Injection of a 5% (mass) aqueous solution of polyethylene oxide into the eyes of rabbits caused only slight burns. PEO had little effect on the death rate of fish, crab, Anemone, shrimp or algae. Its resin and aqueous solution are low toxic, and safe to use and handle. The U.S. Food and Drug Administration (FDA) has approved the use of polyethylene oxide aqueous solution resin for special food packaging and beer direct additives.
