Polyethylene Glycol (PEG)

Description

1. Product Overview
Polyethylene Glycol (PEG) is a versatile, water-soluble polymer derived from ethylene oxide, widely used across pharmaceutical, cosmetic, chemical, and industrial manufacturing sectors. It functions as a solvent, plasticizer, binder, and surfactant, offering exceptional lubricity, stability, and compatibility with a wide range of substances. PEG’s key value proposition lies in its tunable molecular weight, enabling customized performance across diverse applications. Strategically, it is indispensable in modern formulations due to its safety profile, processing efficiency, and adaptability, making it a cornerstone material in high-growth global industries.
