Product Description

Product Description of Polyethylene Glycol CAS#25322-68-3

Polyethylene Glycol is a high-purity industrial product with a minimum purity of 99%. It is available in multiple grades: AEO3 is a colorless liquid and AEO9 is a white paste. Both have a faint fatty odor and belong to nonionic surfactants. AEO3 has a melting point of 5–6 °C and a boiling point of about 290 °C. At 25 °C, its vapor pressure is below 0.1 hPa with a relative density of 0.925–0.940, featuring low volatility and stable physical properties. In terms of solubility, AEO3 is water-dispersible while AEO9 is freely soluble in water. Both dissolve readily in ethanol but are insoluble in kerosene. The product is stable under normal conditions; prolonged contact with strong acids at high temperatures should be avoided.


Product Application of Polyethylene Glycol CAS#25322-68-3

Polyethylene Glycol is extensively applied as a binder, coating agent, dispersant, flavoring aid and plasticizer. It is a clear, colorless, viscous and hygroscopic liquid, or available in white waxy solid and flake forms. Its pH value ranges from 4.0 to 7.5 at a dilution ratio of 1:20. With a molecular weight of approximately 1000, the product is freely soluble in water and compatible with many organic solvents. It is widely used in pharmaceutical, food, cosmetic and industrial formulations, offering excellent compatibility and stable performance.

FAQ

Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.


Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.


Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.


Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
