As a procurement manager or R&D scientist in the chemical and pharmaceutical industries, sourcing high-quality Polyethylene Glycol 4000 (PEG 4000) is paramount for product success. This versatile polymer, known for its excellent water solubility, lubricity, and moisture-retention properties, finds extensive use across various sectors. When looking to buy PEG 4000, understanding key quality parameters and identifying reliable manufacturers and suppliers is crucial.

Understanding Polyethylene Glycol 4000 (PEG 4000) Quality:

When evaluating PEG 4000, pay close attention to its specifications. Key parameters often include average molecular weight (which for PEG 4000 typically ranges from 3600-4400), purity levels (often exceeding 99%), pH, and limits for impurities like ethylene oxide and dioxane. Pharmaceutical-grade PEG 4000, adhering to standards such as USP, EP, or BP, indicates a higher level of purity and suitability for sensitive applications. For industrial uses, understanding the specific grade requirements for your application is equally important.

Key Applications Driving Demand:
