Polyethylene Glycol

CAS no. 25322-68-3


Details

This product is a white granular substance. Soluble in water, soluble in certain organic solvents. Its solution has high viscosity at low concentrations and can be processed by rolling, extrusion, casting, etc. It is a thermoplastic resin with good compatibility with other resins. Resistant to bacterial erosion, with weak hygroscopicity in the atmosphere.

Polyethylene oxide resin is a high molecular weight homopolymer formed by multiphase catalytic ring opening polymerization of ethylene oxide. It can usually be distinguished into those with a relative molecular weight of 2 × 104 or more and those with a molecular weight of tens of thousands or more. The former is called polyethylene glycol, and the latter is called polyethylene oxide. Polyethylene oxide has properties such as flocculation, thickening, slow-release, lubrication, dispersion, retention aid, and water retention. It is suitable for various industries such as pharmaceuticals, fertilizers, papermaking, ceramics, detergents, cosmetics, heat treatment, water treatment, fire protection, and oil extraction. The product is non-toxic and non irritating, and will not retain, deposit, or breed volatile substances during the product generation process. As a papermaking additive, it can improve the retention rate of fillers and fine fibers, and is particularly suitable as a dispersant for long fibers, which can shorten the beating time.
