Polyethylene Glycol 4000 (PEG 4000) is a versatile polymer with a range of properties that make it valuable across various industrial sectors. Its physical form as flakes, combined with its solubility and stability, allows it to be effectively utilized in processes from manufacturing to specialized applications. NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of this industrial chemical, providing quality assurance and technical expertise.

The key physical characteristic of PEG 4000 is its form as white or yellowish flakes. This solid state, with a melting point around 55°C, facilitates easier handling and storage compared to liquid alternatives. Its solubility in water, alcohols, and aromatic solvents is a major advantage in many industrial applications, acting as a solvent, dispersant, or emulsifier. Its insolubility in aliphatic hydrocarbons can also be leveraged in separation processes.

Chemically, PEG 4000 is known for its stability, particularly under conditions lacking oxygen. While it is hygroscopic and can absorb moisture, this trait is manageable with proper storage. Industrial facilities should ensure that PEG 4000 is kept in well-sealed containers, away from humid environments, to prevent clumping and maintain its physical integrity. Adhering to these basic handling protocols is crucial for preserving the quality of the material.

In industrial settings, PEG 4000 finds application as a plasticizer, providing flexibility to various polymer systems. It also serves as an effective lubricant and mold release agent, particularly in the rubber industry, where it helps reduce friction and prevent adhesion during molding processes. This contributes to smoother production cycles and extends the lifespan of molds and equipment.

Furthermore, PEG 4000 is utilized as a dispersant in the formulation of pigments and pesticides, ensuring that solid particles are evenly distributed within liquid or semi-solid matrices. This is vital for achieving consistent color in paints and coatings and for the uniform application of agrochemicals. Its use as a finishing agent in the textile industry also highlights its broad industrial utility.

The shelf life of PEG 4000 is typically a minimum of two years when stored under appropriate conditions. This long shelf life is a significant advantage for industrial consumers, allowing for efficient inventory management and supply chain planning. For businesses seeking a reliable source of industrial-grade PEG 4000, NINGBO INNO PHARMCHEM CO.,LTD. offers a commitment to product quality and consistent availability, making them a valuable partner in industrial chemical procurement.
