二甘醇 High Purity Diethylene Glycol (DEG) 工业级高沸点不饱和聚酯树脂与特种溶剂原料

Diethylene Glycol (DEG, CAS 111-46-6) is a premium, colorless, transparent, and slightly viscous liquid free from mechanical impurities. It is practically odorless with a faint sweet taste and strong hygroscopic attributes. DEG is completely miscible in all proportions with water, ethanol, ether, acetone, and major polar organic solvents. As a highly efficient high-boiling diol derivative, it features extremely low volatility, excellent coupling co-efficiency, and highly reactive chemical properties. In the modern polymer industry, DEG serves as a vital chemical building block for synthesizing unsaturated polyester resins (UPR), polyurethane compounds, advanced polyester polyols, and specialty plasticizers. Concurrently, it operates as an excellent carrier solvent and intermediate in processing textile lubricants, industrial antifreezes, gas dehydration processes, and low-volatility printing inks.

Technical Specifications & Physical Properties

Core Applications

• Synthetic Resins & Polyurethanes: Extensively consumed as a major co-monomer in compounding unsaturated polyester resins (UPR) to significantly improve structural flexibility, impact strength, and weather endurance, as well as polyurethanes (PU) elastomers.

• Low-Volatility Process Solvents: Utilized as a heavy-duty solvent and coalescing coupling agent in formulating lacquers, nitrocellulose coatings, textile printing dyestuffs, and industrial printing inks to deliver perfect drying control.

• Cement Grinding Aids & Metalworking Fluids: Serves as a foundational chemical ingredient in manufacturing modern cement grinding aids to enhance powder fineness and final strength, and functions as a stable coupling component in cutting coolants.

• Gas Dehydration & Antifreeze Agents: Deployed as an efficient liquid desiccant in processing natural gas dehydration plants, and heavily blended into specialized heavy-duty engine antifreezes, industrial de-icing fluids, and hydraulic heat-transfer media.

Packaging & Storage

Packing: Shipped in standard 220 KGS net weight iron or HDPE plastic drums. Wholesale maritime shipping fully supports 1000 KGS IBC containers or large-scale bulk ISO TANK systems for global prompt supply.

Storage: Store inside a cool, dry, and well-aerated dedicated chemical storage facility below 30°C. Keep far away from flames, sparks, intense heat, and direct sunlight. Keep all containers hermetically sealed to prevent moisture absorption and store strictly isolated from powerful oxidizers and acids.
