For businesses operating within the chemical manufacturing, coatings, textiles, and automotive sectors, sourcing high-quality raw materials is paramount. Diethylene Glycol (DEG), a versatile organic compound, plays a crucial role in numerous industrial processes. Understanding how to navigate the procurement of industrial grade DEG can significantly impact your production efficiency and cost-effectiveness. This guide aims to provide insights for purchasing managers and R&D scientists seeking to buy Diethylene Glycol.

Understanding Diethylene Glycol (DEG) Essentials
Diethylene Glycol, identified by CAS number 111-46-6, is a colorless, transparent, and viscous liquid with a high boiling point and excellent solubility. Its chemical structure, featuring two hydroxyl groups and two ether bonds, grants it both hydrophilic and solvent properties. This makes it an indispensable component in various applications, from acting as a solvent in printing inks and coatings to serving as a chemical intermediate in the synthesis of plasticizers and resins.

Key Applications for Industrial Grade DEG
The utility of Diethylene Glycol spans across several key industries:

  • Polyurethane and Resins: DEG is widely used as a chain extender in polyurethanes and as an active diluent for unsaturated polyester resins. Manufacturers producing these materials often seek reliable Diethylene Glycol suppliers for consistent quality.
  • Coatings and Inks: Its properties as a solvent make it valuable in coating formulations, acting as a film-forming aid and viscosity modifier for printing inks.
  • Textile Printing and Dyeing: DEG serves as an effective dye solvent and fiber absorbent, contributing to improved dyeing uniformity in the textile industry. Businesses in this sector frequently inquire about the price of Diethylene Glycol for their formulations.
  • Antifreeze and Heat Transfer: While not a standalone solution, DEG is a crucial component in antifreeze formulations for industrial circulating water systems, often compounded with ethylene glycol or propylene glycol.
  • Chemical Intermediates: It is a fundamental building block for synthesizing other chemicals, including triethylene glycol and certain plasticizers like DEG benzoate.

Sourcing Strategies: What to Look For in a DEG Manufacturer
When looking to purchase Diethylene Glycol, especially in bulk, several factors are critical. Firstly, consider the purity grades available – industrial grade is standard, but high-purity options might be necessary for sensitive applications. Secondly, verify the supplier's production capacity and delivery reliability. A reputable Diethylene Glycol manufacturer in China will offer transparent pricing and robust supply chain management, including just-in-time delivery options.

Navigating Pricing and Quotations
The price of Diethylene Glycol can fluctuate based on market demand, purity, and order volume. It is advisable to request detailed quotes from multiple suppliers. When asking for a quote, specify your required quantity, delivery location, and any particular specifications (e.g., viscosity, freezing point). This will help you secure the most competitive Diethylene Glycol price. Many manufacturers also offer sample testing, which is a vital step before committing to a large purchase.

Safety and Compliance
It is imperative to note that Diethylene Glycol is toxic and strictly prohibited for use in food, drugs, or cosmetics. Always refer to the Material Safety Data Sheet (MSDS) provided by the supplier for detailed handling, storage, and safety information. Ensure your chosen supplier adheres to international standards and provides necessary compliance certifications.
