Polyethylene Glycol 200 (PEG 200) is a fascinating polymer with a unique set of chemical and physical properties that make it indispensable across numerous industrial sectors. For procurement managers and R&D scientists, understanding these properties is key to leveraging PEG 200 effectively. NINGBO INNO PHARMCHEM CO.,LTD., a distinguished supplier of Polyethylene Glycol 200, provides high-quality material and comprehensive information to support your purchasing decisions.

Chemically, PEG 200 is a water-soluble polyether with the molecular formula HO(CH2CH2O)nH, where 'n' averages to approximately 4.5, giving it a molecular weight of around 200. Its defining characteristic is its amphiphilic nature, allowing it to interact with both water and oil-based substances. This makes it an excellent solvent, lubricant, and humectant.

The physical appearance of PEG 200 is a colorless and clear liquid at room temperature, with a low freezing point (below -35°C), ensuring it remains fluid in various conditions. Its hydroxyl value (510-623) indicates the presence of reactive end groups, which are crucial for its use in further chemical modifications or as a component in formulations. Its pH value (5.0-7.0 for a 1% aqueous solution) signifies a neutral profile, important for applications where acidity or alkalinity could be detrimental.

These properties translate into a wide array of applications. In the textile industry, it acts as a softener and antistatic agent. For daily chemicals, it functions as a humectant and viscosity modifier. Its utility extends to organic synthesis as a reaction medium, and it's used in paper and pesticide industries as a wetting agent.

When considering where to buy PEG 200, it's vital to partner with a reputable Polyethylene Glycol 200 manufacturer.
