Polyethylene glycol (PEG) is a water-soluble high-molecular polymer formed by the polymerization of ethylene oxide. Due to its excellent hydrophilicity, biocompatibility and chemical stability, it is widely used in core industries such as pharmaceuticals, daily chemicals, agriculture, rubber and textiles.
As a professional supplier dedicated to the field of fine chemicals, Dotachem offers a full range of PEG products with molecular weights ranging from 200 to 8000+.
The physical properties of PEG are highly dependent on its molecular weight.
PEG-200 to PEG-600: Low molecular weight, liquid. They have low viscosity and excellent water solubility, and are commonly used as excellent solvents, plasticizers and humectants, widely applied in cosmetic and pharmaceutical liquid preparations.
PEG-1000 to PEG-4000: Medium molecular weight, waxy solids. As the molecular weight increases, so do the viscosity and melting point. For instance, PEG-3350 is a commonly used suppository and ointment base in pharmaceuticals, offering good formability and drug release performance.
PEG-6000 and above: High molecular weight, hard solid. It has higher hardness and melting point, and is commonly used as a metal processing aid, tablet lubricant or textile sizing agent, providing excellent lubrication and dispersion effects.
Choosing a reliable PEG supplier is of utmost importance. Correctly selecting the molecular weight specification and ensuring the high purity and batch stability of the product are necessary to fully utilize the performance of PEG in the manufacturing process.
Dotachem can supply a full range of products from PEG-200 to PEG-20000, meeting your diverse needs ranging from cosmetics, pharmaceuticals to industrial applications. We guarantee that every batch of products has high-quality performance. Please feel free to contact us at any time to obtain the detailed product catalogue and technical consultation.
