PEG Polyethylene glycol CAS 25322-68-3

Models are divided according to their molecular weight. Each model has a different performance.

PEG (Polyethylene glycol)


PEG Polyethylene glycol (PEG200600), with a lower relative molecular mass, has excellent solubilization performance, moisture retention and heat carrier. The matrix is often used with high molecular weight, which plays a part in controlling viscosity. melting point and stability.

Product Performance of PEG Polyethyleneglycol

The hydroxyl group at the end of polyethylene is capable of being esterified, among other reactions. The polyoxyethyl can easily be associated with electron-receptors like polyacrylic acid or urea. This will cause automatic oxidation, so an anti-aging agent is required. It is water soluble but the solubility of it decreases when water reaches its boiling point. Also, it is soluble with acetonitrile (carbon tetrachloride), dichloroethane (thermal benzene), and other organic solvants. The molecular distribution of polymers with high molecular masses is extremely wide:Mw/Mn=1520 (Mw heavy average molecular weight,Mn numb average molecular weight). The polymer has a regular structure with spherulite and a crystallinity as high as 95%. Melting point is 6266. Can be extruded. Tensile strengths are close to those of medium density Polyethylene. When relative humidity falls below 70%, the water absorption rate is just below 5%. This almost has no impact on strength.

The polyoxyethyl is water soluble and reduces friction caused by turbulence. It can cut pipe resistance in half with just 6ppm.

PEG Polyethylene glycol


PEG Polyethylene glycol is used as a matrix in cosmetics, a solvent, cosolvent, humectant and viscosity/melting point regulator. Textiles used as lubricants. Softeners, antistatics, wetting agents. Rubber industrial lubricant.

Paper industry: Used as a lubricant or finishing agent. It increases the glossiness and smoothness of the paper. Use in agriculture as a dispersant, wetting agent and emulsifier.

Casting agent for metalworking, lubricants used in metal stamping, drawing and forming, cutting fluids and grinding fluids. Dispersant used in coatings. Ink can be used as a dispersant, solvent and viscosity regulator. Pigment can be used to disperse, emulsify, and also in the synthesis of ester surfactant.
